A world where the Epstein class never dies and don't experiences any consequences. I think we already have movies/series that depicts such a dystopian scenario. Better to delete that class entirely - just in case.
Longevity
A sub about trying to live forever - or die trying.
Unlikely, simply because this would require some pretty major scientific breakthroughs, and most of these breakthroughs happen from scientists collaborating between institutions. Sure, the actual implementation might be developed privately - but the underlying science would be public domain, and it wouldn't be long until there were competitors on the market, shouting from the rooftops and slashing prices.
Yes, I generally more agree with that. Of course, the transition will be somewhat messy and some errors will be made. But generally I consider that it will follow more or less the path as other phisiopathologies, like cancer. In many countries, when someone gets cancer, he / she just gets the treatment. Despite it being freakingly expensive.
First versions of comprehensive treatments will most probably really expensive. And, same as with mobile phones, microwave ovens etc, the economy of scale, experience curve, generally laid down infrastructure and competition will drive costs down and availability will skyrocket. Also, I expect a bunch of those therapies to be eventually paid from public health care - prevention is better that a cure, and healthy people can more contribute to economy (and I hope that governments will value also other things about that, like life itself 🤗).
