I don’t think people want their employee to fail. But given a choice between the most “correct” technology and the most “marketable” technologies. It’s short sighted as employee to choose the most “correct” technology. More than likely the startup is going to fail.
If given a choice between Vue and React, I might prefer Vue. But I would still choose React as a tech lead because I know it is more marketable and you would get more self interested developers and it would be easier to recruit for.
Thanks for giving me clarity into your thought process. I agree the choice between "correct" and "marketable" is a difficult one. Sometimes the most marketable tech is the correct choice. Sometimes the correct choice is the one you and your team knows, even if it is not the most marketable. Sometimes it doesn't matter, because when you are building an app, there are many paths to success.
Technical correctness is not the only factor, there are other kinds of correctness, as you point out with React: "you would get more self interested developers and it would be easier to recruit for".
