My company is in the process of switching from niche language to Python.
The problem is that niche language was a good proxy for "people who have been in the industry / have a lot of domain knowledge / etc".
So our hit rate with the Python dev interviews is like 1/10th of what we had with "niche language" so yes mainstream devs are easier to find, but they are 10x as hard to filter. Further the original excuse was that niche language devs were expensive, but by the time we find a python dev who actually has any domain knowledge & experience, we are paying the same.
