The thing about machine learning is that it’s a vast expertise all on its own. It’s not enough just to read a book. If a company is serious about introducing ml into their product stack then they need people that are experts in data science.
For now at least, there is plenty of room for good engineers that know how to code SOLIDly, are good communicators, are willing to learn their product deeply and are good team mates. That is enough, as it should be.
