I'm quite hopeful that anyone under 40 (arbitrary, mostly because I'm in my mid-30s) will get to LEV (longevity escape velocity) - there's a ton of anti-ageing and disease-curing research going on, especially now with the likes of DeepMind and others accelerating said research.
That's assuming you manage to avoid death from microplastics, climate change or AI-related societal collapse, etc.
In your perspective, why would these drugs be made available to the general public given they'd be arguably the most valuable thing every produced in human history? Presumably one or a few companies would own the IP, so they would of course charge massive sums for them because that's what corporations are supposed to do. So how does that not happen?
