In the short run, yes. However in the long run, their profits have to shrink. They’ll try recovering that from labor. If labor responds with organizing, the oligarchs would see their profits shrink further. Further, the West won’t close up wholesale. Some parts would, others wouldn’t. If people in the insular parts see people having it better across the border, they might vote to have that too. Assuming such a change could happen somewhat democratically. I don’t think the West would be able to insulate long term. But that’s a bet based on a lot of assumptions that could turn out wrong.
I don’t disagree with these points in general. However this isn’t simply about the tools. Tools go along with people and their skill and experience. There are developers and developers. There are people with lots of experience who create much higher quality C code than others. Personally I’d never touch C if I can avoid it as I don’t trust myself as much. I’d always go for C++ instead. Modern C++ with RAII is great. It’s what most of the software at our corpo is written in. Maybe Rust would end up becoming the default standard at some point. Maybe something else would. I would never go shit on a coworker who has produced tons of well functioning code that they better reskill in something that may or may not stick around, or that they may not become as productive with for a long time.
