There is an assumption with some of these responses that you want to learn ML for career progression.

If so, are you really interested in ML or do you just think its the hot bandwagon of the moment which you want to jump on to get ahead? If that is the case, I'd suggest that perhaps that is a bit obvious and to identify something else that is less hyped and mainstream. Perhaps something which you can get ahead of the crowd on and ideally, have genuine interest in.
