Every viral disease may leave long term consequences, including the common flu. So can COVID. But we as a society got quite good at handling common flu. Also most people don't contract it that often and if they do it's a cause for medical attention. Meanwhile people are getting infected with COVID 3-4 times within 4 years and no one bats an eye besides "yeah, you're not lucky". So we were forced into pretending that going through a potentially heavily debilitating disease every 1-2 years is a perfectly normal thing and those who eventually "find out" are either just unfortunate or straight up lying.
Sadly facts don't care about our feelings and social setups. The endgame (that is max percentage of affected people) is at the level of 50% of the entire population with long covid at all times because the damage from subsequent infections accumulates. I just don't remember if the timescale for this was 10 or 20 years of unmitigated spread of the virus (that is: what we have now)
Meanwhile the new mutations are not really less severe. Only vaccinations make it so we're not seeing death rates of 2020 until today. And sooner or later one or another mutated form will evade all immunity, wheteher it emerges tomorrow or in 5 years.
Fun times ahead and, oh, remind me how well are health care systems faring right now when "the pandemic has ended"? Yeah, thought so. And these people are first in line to be affected so it won't be getting better. If anythong COVID is the one topic where doomerism is perfectly justified as we don't even try to pretend we're doing something like we are with climate.
