Would this be an upgrade from an X270?

Docker overhead is practically nothing, so running 3 docker containers should be well within the "light development" bracket.

What the heck is going on here, something cannot be light and use 20gb of memory.

Is LLM driving the RAM shortage or is it hacker news commenters convinced they can't run a single git client without 20gb of free memory.

I am a web dev doing what I'd consider light dev work and the biggest memory hog running for me right now is 2gb for Figma.

What takes 20GB memory? I dev on a 2015 i5 and run multiple docker containers all day without issue.

Isn't docker overhead a full VM unless you're running Linux natively?
