What I see as a problem from the business perspective is that devs are usually thrown into the surrounding of other tech folks and generally this particular tech bubble world we live in. And as someone smart said, for the man with the hammer, everything looks like a nail. Well in 99% of the cases where we split with my CTOs, in the end, wasn't because they were bad programmers, but because they were only keen to solve the issues that they perceived (DevOps, machine learning devops, cloud, encryption). That being said, there are a lot of amazing tech guys out there solving for completely non-tech related problems such as pigeon diapers but that's what it is in the end. It is the problem/solution paradigm, not whether you use rails, AI or blockchain to solve for it. Thats the hurdle I have seen in the past 10 years but maybe I was just unlucky.
