And I think we know people for thousands of years have had these kinds of experiences, looking at mountains and streams and groups of people.

What we don't know is what happens when you take a lot of fentanyl, a lot of methamphetamine, a lot of...

or even nicotine at high levels?

We don't know.

But the worry is, Ben Franklin, it's all things in moderation.

Probably better to take it slow and make sure you didn't overdo this one.

But I don't know what the negative consequences are going to be other than the potential increase in depression and anxiety.

Yeah.

Well, and how you interact with it, what the ways you interact with it, or if the only way to interact with it is flipping the screen, that's pretty limited.

The human body does a lot of amazing things.

The way we can navigate, whether it's

skateboards or paragliding or whatever.

People can do fantastic things with their bodies, but if you're not required to do it, we know this principle of use it or lose it.

If you don't have that exposure to the sounds of Swedish vowels, when we were born, we could hear all the Swedish vowels, and then we weren't raised in a culture that used them, and they just disappeared.

And the worry is that that ability, the natural predisposition of our brains to handle those kinds of inputs, that over time when we don't use it, we'll say, I guess you don't need this.

I guess swimming is not something that you're going to need to do.

I guess – and a lot of people don't swim, which is fine.

But how many of those experiences get turned off, especially at a young age where they're easier to pick up?

That's one of the big questions.

I don't know.
