Adam is super smart. In fact, I asked him for an updated list at dinner a couple of weeks ago and I predict he will be right again.

I'm not going to share my list because I've found that people put too much stock in it. I don't mind talking about things like nuclear energy or biotech, because people are either going to start those companies or not.

But I don't want to cause founders to start or stop working on specific idea because I say something like "I think enterprise software is great" and they really want to get into YC. I never used to worry about this, but I've since found it happens surprisingly often.

The best companies are usually started before any trend is obvious. By the time the trend is obvious, it's too late.
