I actually think right now is the perfect moment for this!

I suspect that the massively increased cost of memory will limit the amount of memory in most consumer PCs from increasing over the next few years. In turn, this will create pressure on developers to memory-optimize their software.

I agree with everything except

> this will create pressure on developers to memory-optimize their software

Ideally, yes, realistically, no. It is rare that I hear FE devs considering how much memory their apps are using. I really wish RAM use would be a much greater concern, but when I look at programs I normally run, I can tell RAM is not a concern (imagine me giving a dramatic accusing look at Docker Desktop, next-server, ...). RAM use for web pages is often not given much consideration either.
