I've thinking into pivoting over to ML/AI for the past year and struggling on 2 fronts. 

1st Front - Ego. Currently I have a good TPM role at a large tech firm with a focus in Project and Product management. Leaving such a role to start from scratch feels like a massive step back / also the prestige of taking a large pay cut potentially in the near term. 

2nd Front  - where to start & what to target? Should I go hardcore technical by learning to Pythons and learn development or target product management/Program Management in the field? 

My background is Engineering, but work has been focused on automotive & Energy jobs. 

What would you recommend I persue & why?
