Do you feel like you've reached the end of what the world has to offer?

no but i feel like i'm being denied it.

Sounds like the dunning-kruger effect. You think you seen it all because you don't know what you don't know.
- I think most in this thread are missing the point. It's not really about specific knowledge, it's about day to day existence and entertainment. The average person isn't deep diving any topic, but nevertheless seeking the next dopamine hit becomes harder and harder and you've seen every core day to day thing by like age 20 which you must then rehash for another 60 years. I get the sentiment.
  
  Yeah, this would be the right answer, the rest is basically the normal copium the humans need to keep themselves going.
  I don't blame them, once you run out of it, life is pretty mediocre.
- This post made me think it would be good if there was a community where people could post about "stuff to do", eg join a local amateur soccer team, here is how leagues work, here is how you find a club to play for, can anyone play, are there min/max ages on teams, are teams split by gender, what is the social scene like, etc etc. Kind of like an AMA but focussed on things people can do if they need an activity/hobby/sport/place-to-meet-new-friends. There's probably heaps of scenes I don't even know about, or don't know how to get involved in.

Not remotely. If you feel like you've seen everything, it might be time to consider a (literal) change of scenery. There are too many places to go, different people to meet and try to understand, books to read, flavors to taste. Seeing it online isn't the same as seeing it in person with your own eyes. You could go a day's walk in any direction and likely find something you haven't seen before. You just have to be looking for it.

this is the wildest statement i've seen all month
the breadth and depth of the experiences that life has to offer is unfathomable. do not be so brazen to assume you have experienced even a tiny drop of vast ocean of what humans have actually lived through
From suicide in the trenches to the raising of a child; from gazing upon Earth from space to hunting a predator with a spear; from meditating in silence for weeks to leading a entire nation through a crisis; from winning a chess tournament to starting a business—and losing it all in a bankruptcy—existence is infinite, or may as well be.
think of it this way
there are 52 cards in a deck. that means every single deck has a specific order, right? what are the chances of you getting one specific order of cards if you shuffle? Well, how many different combinations are there? 52! ( ! means both factorial and emphasis here)
That's 52 × 51 x 50 ... all the way to × 2 × 1
That's 8x10⁶⁷
That's 8 with 67 zeros. Here
80000000000000000000000000000000000000000000000000000000000000000000
For reference.. the number of seconds since the Big Bang is estimated to be about 4×10¹⁷
Now think of your life and human life in general. Think of all the variables. Hell, there are 7 days in a week. 52 weeks in a year. Coincidentally the same as a deck of cards.
If you do something different every week, there are going to be 8000000000......... different ways your year could turn out.
So, please do not fall victim to this type of irrational thought. I’m not sure if it’s arrogance, depression, or something else leading to that delusion, but it’s a wild statement—absolutely nuts
- Meaningfull differences? Who cares how many losing combination of cards you can randomize? There are only fifty-two cards and technically their are only 13 cards ace thru king. To me your argument translates to "look at that dead black kitten, you haven't seen that yesterday it was a dead white kitten." Lulz
  
  i'm kind of lost on how to respond to this. we weren't talking about games, the card analogy was to show that even with a relatively small set of starting conditions you can get to relatively absurd possibilities very quickly. it was to highlight the chaos theory that rules our lives.
  the OP wasn't about winning or losing anything, it was about "having experienced all life has to offer". that would necessarily include both winning and losing combinations, no matter your subjective definition of "winning" or "losing"
  and even having said all that and to follow your analogy- there are many games where drawing a face card (a-k) is a bad thing.
  you ever play rummy? you want the least amount of points at the end of the round and face cards are worth more points.
  you can make a straight flush with a 2 3 4 5 6 in poker, a face card can be enough to bust you in blackjack, etc.

Nope. Almost every day I learn something new.

That is impossible. There are more unique experiences than one can have in their lifetime. Getting a bachelors, meaning really surface level understanding in one topic takes three full time years. If you actually had nothing else to do, you could do that for maybe 15 topics. And that's just learning. What about sports, music, traveling and the endless other human activities.
- Yeah, life is what you make it. Here I am feeling like there isn't enough time to do everything I want to do. Wild how different mindsets can be.
  New experiences keep your mind feeling young and healthy. They also make time move slower. Time flies when everything's mundane. That's how you blink and suddenly you're older. Can't remember what you did because you didn't really do anything. Someone told me this once and I've found it to be very true.

No, in fact I feel like I could be immortal and still never reach that point.
- God, same

My guess is that you have significantly exhausted the extent of your interests and common interactions. It happens.
That's to say, for example, you've read, seen, discussed, etc. almost every sci-fi series in existence. There's some you haven't interacted with but you would have hit the new ones and all the significant older ones. In which case there's really nothing left for you to consume besides minutiae/very small things (you ran the well dry).
The same can said for interactions with people. You're having the same conversations you've had before. Sure some of the specific details change but the core remains the same.
If this at all sounds right, I'd suggest expanding your interests and social circle. For interests, I'd suggest something close to your current interests and look up the highest rated components of that interest to look into. Using the Sci-fi example, fantasy may be a good place to look and Lord of the Rings, Game of Thrones, Mistborn, etc. maybe be good places to start.
For people, expanding your social cycle can be tough. If you haven't already you can try and pair an interest of yours with a group that focuses on that. Example could be RPG gaming and joining a Table Top RPG group. Another option is taking classes in a new interest. You'll likely meet new people with a similar interest as you. Another option is volunteering. There's lots of organizations or mutual aid societies out there that would welcome additional members. That'll give you new people to talk to while helping others (win-win).
Regardless, best of luck with everything :)

The opposite. I'm afraid I will waste my life procrastinating, not even being aware of what it has to offer.

you haven't sucked 4 dicks in a row
- I don't think I will. I'm boring in bed.

Not even close. Too many things to learn, too many things you can get good at, not enough time to do them all.

Yes, you probably should get some therapy about it.

Nah, I wanna fly a plane. Apparantly depression make you ineligible for a pilots licence... 🤷‍♂️
Also the bad eyesight probably isn't gonna make it easier to fly a plane (I have to wear glasses all the time, and I'm too scared for lasik)
As morbid and fucked up as it is, I kinda wanna experience like civil war and just see what coups/revolutions looks like, I mean I'm kinda suicidal anyways, might as well experience something unique.
I wanna see humans land on mars, then permanent colonization and settlement of the moon and mars. Maybe even travel there.
Idk, like I'm just depressed and bored, and no movie or TV show is interesting... 😕
- Regarding the depression. As long as you are conscious about it and have had therapy for it, just lie. Lie to become a pilot if it's really your dream. You know yourself if you are going to be able to learn and drive it.

I can't even keep up with the movies and TV shows I want to watch.
- Agreed, even if you limit yourself to major tentpole content its impossible to keep up.
  But if you look at the uploads to major digital distribution platforms its incredible how much content is being produced:
  YouTube gets 500 hours of video uploaded per minute.
  Spotify has 60k tracks uploaded per day
  Kindle has 225k books published per month
  Steam has 50 games published per day

No. I've completed my personal bucket list though, so I'm never in a great rush to do things these days.

Im no big on new experiences. I like being content. Like a cat. I could never tire of walks or biking or gardening or relaxing or having a hot bath or whatever. I am sad for this world and where its going and even more so that it is my kind. Humanity. Driving it there. Nature is beautiful and terrifying and amazing. I very much appreciate I got to experience this timespace and yet do not want to be of this world.
- You are me. And I also like cats and dogs and have a nice flower garden.
  
  dogs right next to me right now but my wife is allergic so have had no cats in decades. sigh.

Yes I do feel like this. Sure there are things that I haven't done, many involving money or skills that I don't have. Each moment is unique.
But life feels like playing a video game that is procedurally generated. It's superficial variations of the same component things and sensations that I have felt before.
- This is a brilliant description; the feeling OP has is probably on a way more abstract level than most of the comments here are thinking of.

Yes and no. There's always new ways to experience things. I just saw a great concert last night. I knew all the songs, but the presentation changed. People are always creating.

No. We've only scratched the surface of computer-aided collaboration. We could have a crowd thinking space with a consensus development environment, but instead progress has been opposed and we're stuck with primitive wikis. My industry and career are standing still with extreme potential to improve humanity.

Imagination needs expanding. I'm furious I only have a short windows to explore the world And I'm trapped under financial limitations.

Quite the opposite. My two main hobbies are tabletop roleplaying and spending time in nature and both of those have an experience space that can't be explored fully in one lifetime.
I'm often even confused when people seem to think they need to travel far to gain new experiences and I haven't even fully explored the nature just outside of my apartment.

Hell no, not even close.

I doubt I could even make a dent in the amount of art, music, theatre, film, TV, fiction, dance, and reading about scientific studies made only this year so far if I was trying to consume and experience everything.
Let alone everything from the last 200 years. So, no, even without leaving my house there's enough new things to last a lifetime
- Would those experiences provide fulfillment?
  
  frequently, yes. You can't convince me you've never been entertained and enriched by entertainment

OP you probably realize you haven't literally seen/experienced everything in the world. I suspect you've switched from one stage in your life to another. This isn't necessarily a bad thing, but you probably want to talk to a trusted friend / relative / counselor to make sure you're not depressed or something. I gotta say tho that people who "go crazy" as teens and young adults and never stop are sometimes very off-kilter as older people.
- I enjoy the comments in this thread just get a new hobby and ignore your impending death and pointlessness in all this made up societal dogma. OP clearly is just being honest with himself it's called growing up.

One one level, obviously you can never experience everything, the world is fricking massive and ever-changing. But you can feel like you've seen and done everything that interests you, and find it hard to remain curious and develop new interests. There have been times that I think the only interests and goals that will ever feel relevant to me are ones that I've had since I was a kid. But even "eating yummy food, playing games and reading fantasy books" is more than enough to fill my entire life.
When I've been lucky enough to have the time, I've filled many hours, day after day, cooking delicious meals and trying new things in the kitchen, and the list of things I want to try expands just as fast as I tick them off. Similarly, although I've read countless fantasy novels over the decades I've only just got round to reading classics like Conan and Elric, and there's so much more out there - and people write more books every year!
But there are times when I can't face new challenges, and I retreat to the easy comfort of things I know. This can be reassuring and restful, but if I get to the stage where I'm sick of watching the same show I've seen so many times, then I know it's time for me to start pushing myself to try new things and develop new tastes (even if it's just subvarieties of things I already like). And if I don't feel up to that, it means I need to get some support and help to improve my mood and clear my thinking.

OP, just how wealthy are you? This is a very rich person assessment to make.
- I make $700 a week at Amazon and $200 a week with DoorDash but I still don't have my own apartment. On the plus side I have several months of expenses saved so I can take days off anytime (amazon is flexible as hell) but I really need to live alone where I can optimize my life for maximum peace and receive mail in my legal name. I really want (and need) to live in an apartment close enough to my warehouse that I can walk, bike, or ride public transit for less than 30 minutes. Preferably riding a bike or escooter in the early afternoon like whooooooosh
  I'm not broke but I'm not ultra I Can't See The Ground From My Window And My Dog Is My Alarm Clock rich. Not yet anyway, I will not stop trying to make money until I live in a multimillion dollar palace in the sky with like 10 bedrooms that are all mine, my animals', and my husband's.
  Tl;dr I make $700 weekly and more if the stars align
  
  You haven't even bought a house.
  Seen everything, my ass. You're fucking bored, go do some shit.

I’ve only been to 8 countries, so no.
- I been traveling for a long time. The magic is gone, McDonald's is global. All the woman try to look like Kim Kardashian. All the men wanna drive the same cars and wear the same designer clothes. They all peddle the same corporate constructed music. Everyone watches the same shit on Instagram/TikTok and goes and stands in lines to take a dumb ass selfie. Everyone speaks google translate. Now excuse me I need to google map a restaurant for dinner.
  
  lol, you aren't traveling to the right places or something, or I think more likely you're depressed if you feel this way.
  There have always been trends and conformity throughout human history. 🤷‍♂️

Not really? Always something else beyond the horizon.

i find life so unsatisfying that if, when i die, the afterlife has any resemblance AT ALL to this current reality, i am going to be fucking pissed.
like, any version of occupying a physical body in some sort of 3-dimensional space and surrounded by other physical beings is just, so.... ugh.
i am over it.
- Hood news. The afterlife is the same thing as the before life. Remember that? The 4 biillion odd years or so before you existed? Exactly.
  
  Pre-universe non-existence: "Am I a joke to you?"

No, not at all. I've travelled extensively (maybe 75 countries) and had reams of wild experiences, but I've not seen a fraction of what the world has to offer.

No.
I still want to travel more.
I want to pursue music in some small way, at least, even if only a few local shows here and there, to say I did it and to really experience it.
I'd like to see my book published someday, even if it generally flops, because I would like the ideas out there.
I'd like to see my kids establish themselves as adults and help with that process, even if it might not end up as extravagant as I'd liked.
I'd like to meet someone really cool again and have an awesome relationship, having learned pretty well what works and what doesn't, by now. Maybe.
I want to try like 10 jobs I haven't, yet. Do I still have time to be a doctor? Maybe! We'll see!

Not really, the bucket list only gets longer

What percentage of people do you think on earth have the magic glass connecting them instantly with each other and their shitty lowest common denominator ideas? Of the people who don't have the magic glass, I'd still wager they are all very similar: hunt, gather, shelter. So I will agree there are two archetypes. Magic glass slaves and people who only have time for survival. Tear the blindfold back face reality all humans are the same, or take the blue pill and wake up in your bed... Also you think a guy named alcoholic could be depressed lol in this world I'd imagine that is the correct state and perhaps we are over prescribed happy pills and pushed distractions to keep society fat dumb and "happy".
- People only with time for survival often have more spare time than magic glass people.
  
  Idk buddy I never seen a fat survival person, I think that is a harder life than you think. Just because they have to rest doesn't means it's relaxing.

Get into folkloristics, it's pretty fun. You can get into all the Slenderman stuff because it's literally untapped mystery you can't just rely on secondhand sources, all the research is centered on one controversy that somehow killed his popularity but not every other religion. My "job" (it's a hobby) is basically having to read the hundreds of all the Slenderman blog ARGs ranging from 2009 to the present day, as well as all the freaking Slenderman and Creepypasta comics. It's just interesting how religious patterns emerge out of something spontaneously created on the internet, like Zalgo vs Slenderman having parallels with every other religion with "divine rivalry". Interesting anthropological subject.
- Or you can read world history that isn't just Eurocentric stuff. Hell, I bet most people don't know European History in depth. You can even get into scholarly theology, from Christianity to Hinduism (which btw, is more of an umbrella term as it is composed of multiple religions). Read philosophies like Confucianism, which will help you understand a bit of Chinese culture.

A card game is still a card game. Slight variation on the rules doesn't make it dynamical better or new and exciting. I suppose if your easily amused "look this king has a sword that he is cutting his head off with. " "It used to be an axe you know." And I found a profound amount of joy in that.
