An issue with this tweet is that we already have the capacity to do a lot. We have the technology to provide healthy and diverse diets for the entire planet and fit a cities worth of farming inside a few city blocks (vertical hydroponics/aeroponics). We have the ability to create electricity in a dozen different renewable ways. We have the ability to desalinate water creating nearly infinite fresh water, we have enough square footage in the world to easily house everyone. We have stellar education systems that we could hand out to the entire world.
Why don't we do it? Well, all these things cost money. But the issue is, there also exists staggering amounts of money across the world. The panama papers revealed just a fraction of the wealth being hoarded by just a fraction of the wealthiest people in the world (and most implicated in the panema papers weren't even too crazy, like soccer stars and business owners). There's exists tens to hundreds of trillions of dollars of wealth created by the world just floating around in billionaires bank accounts and in the coffers of world powers.
So it's not an issue of abundance coming in the near future, we have it here on earth right now.
