Yes, I understand! I'm talking from the perspective of someone that learned those skills.

That learned about tool chains, about the required infrastructure, the processes, IDE configuration, etc.

I'm not saying the change is painless. I'm saying for each of those, there's an equivalent in any other game making tool. The foundations help to learn the new ones faster. And the new ones takes you generalised knowledge further. Which only contributes to your professionals growth.

At the end of the day, every technology will be replaced. Being able to transfer skills between different scenarios is a valuable skill itself. :)
