Ask HN: Med student interested in bci startups..where do I start?

I am a First yr med student at aiims in india am 20 yrs old.My long term goal is to have a bci startup and the reason is I was always interested in innovation and intersection of tech and med but I never really got the exposure Cuz med students are often told to be defined and follow the system but I think there is More to us than just following convention protocols and especially in this ai generation I think its really important to be interdisciplinary(I have a python background and technical stack such as signal processing and mne python.Lookin for advice on how to approach dis as a med student and what would u do if u were in my position
