I guess there's worse outcomes.

But I guess in software, I almost feel like it's almost unbounded how terrible some things could be.

So I do think that they share that property.

And then I think basically what takes the long amount of time and the way to think about it is that it's a march of nines, and every single nine is a constant amount of work.

So every single nine is the same amount of work.

So when you get a demo and something works 90% of the time, that's just the first nine.

And then you need a second nine, a third nine, fourth nine, fifth nine.

And while I was at Tesla for, was it five years or so, I think we went through maybe three nines, two nines, I don't know what it is.

But like multiple nines of iteration, there's still more nines to go.

And so that's why these things take so long.

And so it's definitely formative for me, like seeing something that was a demo.

I'm very unimpressed by demos.

So whenever I see demos of anything, I'm extremely unimpressed by that.

It works better if you can, if it's a demo that someone cooked up and is just showing you its worst.

If you can interact with it, it's a bit better.

But even then, you're not done.

You need actual product.

It's going to face all these challenges when it comes in contact with reality and all these different pockets of behavior that need patching.

And so I think we're going to see all that stuff play out.

It's a march of nines.
