Ask HN: PhD Machine Learning vs. MBA

I am a 25 year old software engineer with a Masters degree in Computer Science from University of Cambridge along with a few years of Software development experience.

I have identified that my passion lies in startups - especially in the intersection of product, people and technology - hence I think an MBA in the future would be a good career option for me.

I currently have a PhD offer from the University of Cambridge in Speech Processing and Machine Learning and considering whether it would be a wise career move given that I'll be 28-29 when I finish.

Any advice from someone who has gone through a similar situation would be invaluable. Thanks!
