I was thinking the opposite: it's actually surprising how long 16 GB has remained a useful amount of RAM? At home I use a 10 year old 16 GB laptop and the amount of RAM never seems to be the problem. Any sloth is always due to one or both of the outdated GPU and outdated CPU.
(First time I bought a PC with 16 GB RAM was 2011. It wasn't a ridiculous amount of RAM back then, just usefully more than necessary. 16 GB has probably been a sensible amount for 15 years now.)
(Whether I'd buy a computer today with 16 GB of soldered-in non-upgradeable RAM - that's another question. And my answer would be: I wouldn't. However that is not because it would be useless on day of purchase!)
