"it would never cross my mind to make a blanket statement that all engineers should work at startups" --> I completely agree. In fact, such blanket statements about almost any kind of advice is often naive.
I like the end of the posting, as well as most of the comments in this thread.
VCs have a job to do, just like everyone else. Sometimes they need to make hard decisions.
It's important for every business professional (entrepreneur or anybody else) to understand the basics of other people's goals and incentives.
I have a top-5 MBA. In hindsight, I am torn.
A big part of me believes "you don't need an MBA to be successful in tech" (etc etc etc).
However, every week I use tools & skills that I picked up during my MBA. Yes, sometimes it has to do with modelling and such stereotypical MBA skills. Many other times my MBA has a much larger impact - recalling the themes that were incessantly driven into me in my Managerial Leadership class, or enforcing the rigor that my Marketing prof required of his students when writing positioning statements.
I believe my MBA has increased the likelihood of me being successful. That's what matters to me. I agree that it's not for everyone.
The UX world has struggled to find its best fit in Agile. At SIGCHI Montreal a few years ago, it was a big topic of discussion where pain points were discussed much more than proposed solutions. I like Jeff Patton's view on UX in Agile, which is in the same vein as the 3 points you wrote down.
