I like retro computers as much as the next person but selling dead technology and brands just doesn’t make sense.

About writing a Commodore C64 game in modern(ish) C++
maybe it will sway you a bit :-)
No negative or positive comment on its usability though, I'm not an ML/Neural Network simulation person.
Coming from a background of working with OS kernels and systems software, I don't mind the kind of explicit "C++ lite" style used by the OP. Left to my own devices, I usually write things that way. I would think twice if I was trying to design a large framework, but ... I try to avoid those.
There's no source of that signal that someone is open to chitchat these days, and it's in my opinion kind of killed what was once great about online communication.
