I realise it's how things are today and not going to change any time soon, but it still feels like we as an industry have moved all too easily in a very wasteful direction. Sure, with RAM you can just buy more, but it's symptomatic of a wider malaise. Other capacities, particularly CPU core speeds, have long since stopped increasing on a nice exponential-looking curve to compensate for writing ever more layers of ever more bloated software in the name of (presumed) greater programmer efficiency. It just feels like we've lost the kind of clever, efficient culture that we used to have, and I'm not sure we weren't sold a bill of goods in return.
I'm not sure whether curve is still exponential or not, but it's there. Single-thread performance is increasing every year a little bit and core count is increasing like never before. 16 cores consumer CPU is not a dream anymore.
RAM size slowly increases as well. 4 GB was enough 10 years ago. 8 GB was enough few years ago. Today I would suggest 16 GB as a bare future-proof minimum and one can buy 64 GB for a reasonable price.
We still have room for more layers. And it's not only about efficiency, it's also about security. Desktops are still not properly sandboxed, my calc.exe still can access my private ssh key.
Once performance growth will really stop, we will start to optimize. Transistor density will double every few years until at least 2030 and AFAIK there are plans beyond that, so probably not soon.
