Maybe we'll get into some of that.

I'm not sure where you want to take the conversation.

But that was for about six years.

And then I joined Meta Reality Labs.

You've seen these glasses that they have.

Uh-huh.

The new version has this wristband and that wristband reads out your muscle signals.

It's basically like controlling a device just by gesturing or like writing.

That doesn't seem on prima facie that hard in that we know what signals are going to get sent to the messages to move the hands in some way.

Conceptually, it doesn't seem that abstract.

conceptually, if the signals are there, you can machine learn them and pull it out.

There are reasons it's hard, but first let me meet you on the conceptually, no, it's not like doing brain-machine interfaces where you have no idea what's going on.

Right, because it's very like end of river.

Exactly right.

It is true that your motor cortex projects to your spine, the spine projects to your wrist.

The muscle is driven by electricity when you move, and that's an aggregate signal of neurons.

Those are the cells in your brain that fire electrically and cause you to be you.

But to meet your point, what's coming down the line here is not

your pancakes that you had for breakfast.

It's the stuff that you do to move your hand.
