The most demoralizing thing was the phoniness. The pointlessness of it all. Everybody was just going through the motions. The only thing people wanted to know was the exact sequence of steps they had to follow in order to achieve success. Everybody here knows you have to go to school in order to not be a nobody. So everyone goes to school. It barely matters what field they pick, anything will do. The more prestigious the better. People go to these places and they study crap they don't actually care about because it's all just a means to an end.
I was constantly surrounded by people who I felt didn't actually enjoy computers as much as I did. Made me so disillusioned I chose to do something else with my life. I just couldn't bear to be around people like that anymore.

The problem is real. But it is not something unknown in other countries.
What US has in superior is the mentoring culture, the business people interwoven in the university culture (like the extra courses offered in Sloan with real companies!), the sharp focus on patent, other things. But technical knowledge in top Brazilian universities will compete or outclass technical knowledge in US. But there are many things important, supporting things, a whole infrastructure beyond the technical people required to advanced technology.
