That’s why now it’s legitimate to work on multiple features or projects at the same time
(Also, this only applies if what you're working on happens to be easily parallelizable _and_ you're part of the extremely privileged subset of SV software engineers. Try getting two Android Studios/XCodes/Clang builds in parallel without 128GB of RAM, see what happens).
But yeah improving build speed & parallel running I think are one of the biggest advances devs can do to speed up development time in the AI age. With native apps that can be a challenge. I restructured a react native project to make it faster to iterate, but I have a feeling you might not be fond of rn.
With all due respect, the commment does carry the vibes of "it's okay I can totally multitask" that's nearly a cliche in programming. It just feels a bit insensitive to respond to an article talking about context switching being a big problem with LLMs and then suggest the biggest possible context switch of managing multiple workstations.
And yes, your hardware expenditure will vary per industry. I can barely run one instance of Unreal Engine as is.
