Oddbean new post about login | logout I've seen a lot of "I've spent years learning this tool and now it's wasted". Majority of that gamedev knowledge is transferable, it's not gone. It might be different on a new tool but you'll know how to do it, it's easier to search the equivalent then not knowing at all.
@eb948c00 It was transferable skills that got me *into* Unity. I already knew C# through the .net stack and I'm still a full-time applications developer. Even then, if the whole C# ecosystem crashed, I know I can transfer my skills over to any language or tech stack and become proficient in a very short time. You just have to be willing to make the leap and, importantly, be okay with making basic mistakes again for a while.
I think developers who started gamedev with Unity, and only used that for years might be a bit more scared since that's all they know. But listen, that tool doesn't define your work, it's just a tool used with your creativity. Did it helped a bunch by doing stuff for us? Yes. Can you now learn something else much quicker? Absolutely.
