Steam is about creating tools for content creators and customers.

Computing lets people express their creativity and unlock solutions, and code is computing's universal language. All young people, including girls, deserve to be fluent in the language of the future.

When I worked at Microsoft, I got to go and visit a bunch of different companies. Probably a hundred different companies a year. You'd see all the different ways they'd work. The guys who did Ventura Publisher one day, and then United Airlines the next. You'd see the 12 guys in Texas doing Doom, and then you'd go see Aetna life insurance.

About half the people at Valve have run their own companies, so they always have the option not just to take a job at another game company, but to go start their own company. The question you always have to answer is, 'How are we making these people more valuable than they would be elsewhere?'

If you look at a multi-player game, it's the people who are playing the game who are often more valuable than all of the animations and models and game logic that's associated with it.

It feels a little bit funny coming here and telling you guys that Linux and open source are the future of gaming. It's sort of like going to Rome and teaching Catholicism to the pope.

I think it's really clear that Sony lost track of what customers and what developers wanted. I'd say, even at this late date, they should just cancel it and do a do over. Just say, 'This was a horrible disaster and we're sorry and we're going to stop selling this and stop trying to convince people to develop for it'.
