You'd think that someone like Bill Gates, who clearly started a technology company,

that's one of the biggest companies in the world, Microsoft, you'd think he'd be really quite

strong in the sciences. But actually, at least direct conversations with him,

he is not strong in the sciences. Yeah, this is really surprising.

You know, like, he came to visit me at the Tesla Gigafactory in Austin,

and was telling me that it's impossible to have a long range semi truck. And I was like, well,

but we literally have them. And you can drive them and Pepsi is literally using them right now.

And you can drive them yourself or send someone else to drive himself. But you can send a

trusted person to drive the truck and verify that it can do the things that we say it's doing.

And it's like, no, no, it doesn't work doesn't work. I'm like, okay, I'm like, kind of there.

That is like, I was like, well, so it must be that you disagree with the watt hours per kilogram of

the battery pack so that you must think that perhaps we can't achieve the energy density

of the battery pack, or that the watt hours per mile of the truck is too high.

And that when you combine those two numbers, the range is low. And so which one of those numbers

do you think we have wrong? And what numbers do you think are correct? And he didn't know any of

the numbers. And I'm like, well, then doesn't it seem that it's perhaps, you know, premature to

conclude that long range semi cannot work if you do not know the energy density of the battery pack

or the energy efficiency of the truck chassis.
