I’m a PM & designer in his late 30s who is itching to get into deep tech (BCI, AI, aerospace, medtech, etc). I have no background in engineering and am considering pursuing a masters either in CS or similar.
Has anyone here done this mid-career? Was it worth it?
And while you'll absolutely learn some things and find yourself excited about some ideas in those couple years, you will forget almost all of the stuff your learned within a few years of graduating because you won't be continuing to get your hands dirty and won't be building on the knowledge. Technical knowledge does not "stick" if you don't use it.
If you're a hungry learner and have the free time and money, you can go back to school for whatever you want. This sounds adjacent to your work, at least, so that's something. But remember that formal education is only the first and smallest step in learning a technical discipline, and it sounds like you want to continue PM'ing rather than transition to a technical IC, so you won't be continuing on the later steps.
If you're just trying to be the best technical PM you can be in your industry, there are almost certainly far more time/cost/stress-efficient ways to do so.
