I jumped from ML ( 2 years) to MLoPs ( 1 year) then to backend engineering (1 year) . Now I am planning to come back to ML. Mostly worked with CV was bit bored since we mostly used off the shelf models, but other endeavours turned out to be more boring for me . It's my personal opinion, there's nothing wrong with the fields. I don't find it intellectually challenging. For me it was bit stressful because it seems there were lot of systems in place which created complexities. Coming back to ML, because I feel it satisfying ( although it has its cons) but I do enjoy it more than the other fields that I have tried.
