I was curious about the tape actually means. It feels like… When I think about AI predictions, one thing I'm really struck by is how, still in 2026, every time you open a chat window, it's contextless.

The product we aim to build is far ahead on throughput, but then, actually, the surprising thing is we're competitive with the best on latency as well. I think that is a unique thing in offering both in the same place.

There's what the Rust marketing will say, which is "safe without a garbage collection," which I think is a real… It is the objective thing that you can say is different, but sort of buries the lead, which is also just it's got nice type system features that Go doesn't have.

We think probably the main thing will be similar to where NVIDIA is at, which is 4-bit precision. But I think a mix of different precisions is useful for just when you look at the research, sometimes you want some layers in higher precision or lower precision, and so on.

I think that's a pretty good fit because you have different parts of your company that are skilled at different areas, and it allows you to keep both of them occupied without having instead every 2 years doing a massive risk release.

What that means for us is that ecosystem already exists, and that way of operating, where you say, "I'm just going to staff a 50-person team to write software for this chip," works really well if you're trying to sell to frontier labs.

There's this really cool technique called 'cuckoo hashing' where you hash into two different locations, and then you use the bucket which is less full. It's been in the literature for decades and yet the best hash table implementations don't use it because it's somehow not practical.

I think most ML researchers, especially of the time, were not super deep in what hardware wants, and what is… Mechanical sympathy is sometimes a term that's used for that.

I don't know if they've talked about this stuff publicly, but you know that their internal metrics similarly show that the faster the product page loads, the more people buy it.

Exactly, the repair thing, it feels like, can be solved, because also, I think part of the bet, part of Elon's claim, is that we will just be so power-limited that you have no option but to go to space.
