Quoting Paul Graham

A lot of the emails I get from founders are now written in a hard-hitting journalistic style. I know they're written by AI, because no founder ever wrote this way before. And once you realize something is written by AI, it's hard not to ignore it.

I have never knowingly finished reading an email signed by a human but written by AI. It feels like being lied to, and who would stand for that?

[...] It makes me think less of the author. It means they can't write well unaided (or feel they can't), and that they're trying to trick me.

It's not impressive to use AI to write stuff for you; any teenager can do that.

Building an AI Data Center in Pine Island, Minnesota

"I learned about the data center as soon as the scrappy sign was erected. I was thrilled to see something new; my drive hasn’t changed much in three years. I was less thrilled for Pine Island, which has, like many rural Midwestern towns, become an unlikely microcosm of the AI debate."

Quoting Corey Quinn

I cannot believe I'm saying this, but getting the literal Pope to canonize your product's specific technical limitations as a spiritual treatise is the single greatest act of vendor lobbying I have ever seen.
