So you'd rather spend four years of your life at a school which stymies your growth rather that nourishes it? I'd much rather make a decision to spend four precious years based on whether or not I feel like I would benefit, not because Bill Gates did.
No, I'd rather keep discussions mature. It "feels good" to devolve into diatribes, and trust me, if you know me, I HAVE... but the question here is "what undergrad schools should I consider."
Back on topic, empirically, I know many people involved in startups with _some_ connection to Stanford, probably more so than any other single school. I know many people from UC Santa Cruz, too. Both may be because these are the two nearest good universities near Silicon Valley.
Not so many from San Jose State University. Maybe stay away from that one.
How could I say that attending SJSU precludes one from success? I'm saying if one could attend either SJSU or UCSC that SJSU may not be the best choice generally even though SJSU is closer to silicon valley.
