Replace C++ with asbestos (no, I'm serious, not just stark), and we're basically having exactly the same conversation that's gone on over decades in the meatspace world, with analogous players, sunk cost/investment calculus, and migration consternation. The only part of the conversation that is missing is the liability conversation and damages.

And I do take asbestos as a serious example. Asbestos is still manufactured and used! Believe or not there are "safe" uses of asbestos and there are protocols around using them. Nevermind the fact that there is a lot of FUD and dishonesty about where exactly the line cuts on what is safe versus not safe...for example we are finding out how brake dust affects the wider environment as we crawl out from under the tent of utter misinformation of a highly motivated entrenched industry.

I feel like this is not a new human phenomenon. We made particularly poor choices in what tech we became dependent on, and lo and behold, the entrenched interests keep telling us it's not that bad and we should keep doing it because...reasons.

It will eventually play out the way it must; C++ might seem a lot more innocuous than asbestos, and in some ways that's true, but it resists all effort to reform it and will probably end up needing to just be phased out.
