How to judge if colleges are dead and no one cares about them anymore: Go to your LinkedIn connections and check how many of them have this: IIM X, IIT Y on their bio. You will have your answer.
See what people do instead of what you read on Twitter.
Another thing to observe: Are kids of company execs and VCs creating their distribution on Twitter (shouting colleges are dead) or are they going for their Ivy league education?
Also why I am grateful I went to BITS
Not saying you can’t make it without a college education or an MBA, just do your own research.
