I'm CNN tech reporter Claire Duffy.

I cover artificial intelligence and other new technologies for a living.

And even I sometimes get overwhelmed trying to keep up with it all and stay safe in the process.

On the podcast, Terms of Service, we can explore how to experiment with these new tools

without getting played by them. Listen to CNN's Terms of Service wherever you get your podcasts.

If you happen to be super sexy or super wealthy, evolutionary psychology suggests you will have your pick of lovers and live happily ever after. But if that's true, why are there so many spectacular breakups in Hollywood and Silicon Valley? And if everyone's

romantic relationships, maybe you can start by reminding us of the stereotypical interpretation,

And that includes things like everybody has a mate value, a certain set of traits and attributes that make them either desirable or not in the mating game. Another idea is that men and women are these very different creatures
