You understand: You saw the move 'Wall Street', right? So, what was the probability of a big move up of the PA steel company? Low, right? "A dog with fleas". But the conditional probability given that the takeover guy's plane was flying to PA was quite high. Got it now?
Again, yet again, to repeat just for you, from my three examples in my post, it's possible to plan effectively, even for advanced projects, and then perform according to plan with relatively low risk.
On picking winners, VCs don't try very hard to evaluate projects. E.g., recently a VC told me that he sees a lot of projects that currently have $2000 a month in revenue. Thus he missed the point: No doubt at one time each of Apple, Microsoft, Google, and Facebook had about $2000 a month in revenue. What is just crucial in picking "winners" is essentially to f'get about the $2000 a month and look closely at the project. VCs don't like to do that. Moreover, in recent years in information technology projects, VCs just don't want to believe that there could be any advanced, solid, unique, powerful, valuable technology difficult to duplicate or equal to be evaluated. Evaluating technology and projects just isn't how their business model works.
On my startup experience, you were guessing and guessed incorrectly.
