For example, I was a little surprised when I was talking to a friend who was going to go on the radio. He does work on cosmology and astronomy, and he wondered how he would explain what the applications of this work were. "Well," I said, "there aren't any." He said, "Yes, but then we won't get support for more research of this kind." I think that's kind of dishonest. If you're representing yourself as a scientist, then you should explain to the layman what you're doing—and if they don't want to support you under those circumstances, then that's their decision.

every time I heard the word “smart” attached to anything, it means it’s pretty dumb, because no one knows what it really does. They just add “smart” as a prefix to say, “Oh, you must buy this, because it’s smart.” If they can’t tell you what it does and why it does it, don’t buy it just because it says “smart.”

Our culture lionizes entrepreneurs who navigate daring switchbacks in their career. Steve Jobs was admired not just for Apple, but also his detour to found Pixar. Elon Musk is revered for helming Tesla AND SpaceX. But don't be distracted by other people's winding paths. I believe you should celebrate your single-mindedness, and stick to your own overarching idea — for as long as it holds your own fascination. In my experience, that could last your entire career.

AI without validation is too unreliable to be of use in any serious application.

I think it begins as a kind of tension in space.  There’s something out there and it’s waiting for the big bang, and I have to get that into my head.  I have a composer friend in Ireland, and he beautifully said, “I have this scream in my head and I have to get it into the orchestra.  I have to get it into the music.”  But I wouldn’t be quite as dramatic as that.  But I have this tension.  I have this thing that has to be done. And the problem is, you see, once you’ve got the first paragraph down and you’ve got the tone, then the bloody book is written.  All you have to do is fill it in then, which makes it really boring.  I mean I’d like to be like one of those Japanese artists, you know, just go shoop ! and it’s done.  But no, it takes years.

I keep office hours. I work from 9:30 to 6:00. It’s curious. In the morning, I could just about tie my shoelaces before noon, but I can write. It’s obviously a different part of my brain that’s working.

Anyway, what’s the point of a plot, you know? Has life got a plot? Not that I know of. So why should a novel have a plot? But it has to have some kind of story. It has to have some kind of structure.
