Its already like this. My first job in the 90s I wrote our own linked list classes, a logging framework and a persistence layer. Now it feels like I write css and yaml all day.
You still get to do something as close to the metal as writing raw CSS? I'm reliably told that's cavalier and you should be writing something that compiles to CSS.
By the way, the HiSOFT that created DevPac 4 (assembler/debugger) for the ZX Spectrum is still around. According to their about page they now build websites?!? https://www.hisoft.co.uk/
