I agree entirely. I was just using my old system as a beefier example of the OP’s from the same generation and how a now modest desktop compares.
Yeah, if I did that I’d spend more time proofreading, fixing bugs, and rewriting incorrect sections than it’d take to just write the code correctly on my own. I can see potential under all the hype but, at anything like the present rate of incremental improvement, it’ll still be me doing most of the coding for years.
For my projects, where I need a lot of main memory bandwidth, a fleet of desktops is still cheaper than buying HEDT or server class systems. Modern systems keep getting more and more memory bandwidth starved, but at least low core count parts still exist. But I’m not compiling code, where core frequency tends to matter more.
I do suggest spending money on a good NVMe drive. If everything is cached, read latency won’t matter, but some software will have frequent disk syncing.
