OpenAI buys all the RAM driving up the price so their models can shit out poorly optimized software so I have to buy more RAM. Awesome.

Agreed - it's more likely to lead to poor user experience than anything else. Most end-user facing software/service companies will probably bet on the DRAM price peak being temporary.

Software takes a lot of time to build. Codebases live for decades. There's often an impossibly large cost in starting over with a less wasteful architecture/language/etc. Think going from an Electron/Chromium app to something built using some compiled language and native OS GUI constructs that uses 10x less resources.
