I come from a more traditional (PhD) ML/DL background. I wouldn't recommend getting into (1) because the field is incredibly saturated. We have hundreds of new, mostly low quality, papers each day. If you want to get into AI/ML on a more fundamental level now is probably the worst time in terms of competition. There are probably 100x more people in this field than there are jobs, and most of them have a stronger background than you if you are just starting out.
