Once you’re allowed to do that, people who want to get rich can do it by generating wealth instead of stealing it. - Paul Graham

I think that, like species, languages will form evolutionary trees, with dead-ends branching off all over. We can see this happening already. Cobol, for all its sometime popularity, does not seem to have any intellectual descendants. It is an evolutionary dead-end — a Neanderthal language. I predict a similar fate for Java. People sometimes send me mail saying, “How can you say that Java won’t turn out to be a successful language? It’s already a successful language.” And I admit that it is, if you measure success by shelf space taken up by books on it, or by the number of undergrads who believe they have to learn it to get a job. When I say Java won’t turn out to be a successful language, I mean something more specific: that Java will turn out to be an evolutionary dead-end, like Cobol.

Data is ideology's headwind.

I'm always looking for ways to add network effects to a startup's idea. Investors love those. But network effects are genuinely good to have. So any we come up with in order to feed to investors, they should probably go and make happen.
