It all depends on quality of life in those extra years. Like if aging becomes obsolete, and is reversible, it will change everything. I’m sure that’s what it will pitched as, but if it makes my seventies last decades, no thanks. The monetization of it is what will be interesting. I’m sure it won’t be a one time cost thing. Like if it’s here’s $30k, and now you’re 25 for 50 years, hell yeah. But it will probably be a subscription service, and be some sort of In Time dystopia.
