And then Gen Z is from? I say 1996. Pew says 1997. Who knows? You can't say, but roughly 1996. Gene Twenge says 1995. So if you're born in the mid nineties or later, you are Gen Z. And what I came to see is the key thing is look at early puberty. If you were born in 1995, last of the millennials, you're turning 15 in 2010. You probably had a flip phone. You didn't have Instagram. in 2010.

And you might've traded in later, but the point is you made it most of the way through puberty before the great transformation, before the great wiring. And you didn't get this stuff until really more like college. Your mental health is probably fine. But if you were born in the year 2000, you turned 15 in 2015. And so your first phone might well have been a smartphone.

And the iPhone gets a front facing camera in 2010. And Instagram comes out in 2010, but Facebook buys it in 2012. That's when everyone goes on it. If you were born in the year 2000, you went through early puberty as a girl, especially on Instagram with your phone in your hand. Half of our teenagers say they are online almost constantly, phones always in their hand.

I mean, I was always just thinking about Gen Z, but we don't know when Gen Alpha begins. Marketers tell us 2010 or 2011. I think it might actually depend more on TikTok. I think TikTok is transformative for brain development. And so it might be that the generation shaped by TikTok is very different. But for now, we're going with 2010. Let's say 2011 is the first birth year of Gen Alpha.
