Money and time.
Tons of people build cool projects during their time in university, but the vast vast majority of people don’t because they are eating beans and rice and ramen and pizza and studying, not spending 500€-1000€ on iterative prototyping and the equipment to test everything.
I listen to his podcast weekly. I haven’t listened to the one from the OP, but in the past year I have become very disillusioned with Stewart.
Every interview is an absolute softball “what’s your favorite color” BS where each and every answer is a boot that is slobbered on with “BAM”, and “BARS” and every misdirect and deflection by the guest is just accepted and the root of the few harder questions goes unanswered without protest outside of maybe the Christie interview.
The Jeffries interview was absolutely embarrassing, for example.
It’s very different from Stewart 15+ years ago.
