Where are the GenZ multi millionaires and billionaires?

It goes in cycles. The late 90s into 2010s was getting everyone "online" 2010s to 2015s was "online stuff" and 2013 today has been moving all the software to the internet, people got rich in each wave of them. I wish I could find it but I once saw a super early day interview (not the Bambi Francisco one) of Zuck asking about turning down billions and he's just like "I have facebook..." - he could see what was in front of him. Personally I'd guess the next big wave of young rich folks will come out of hardware. On your comment about content creation/the creator economy... I hope for a resurgence of the value of individual art and creativity. The greatest joy I had working on building deviantart was technology disappearing into the background so creativity could shine. Now that we have a sort of interesting tech maslow in place, I hope many young folks are able to find ways to make comfortable livings doing cool things using tech over the next 10 years, and I hope we continue to de-emphsize the want to become a billionaire, the richest people I know are the least happy.

I think you really can't make that kind of money at content creation or crypto.

Remember Zuckerberg, Gates, Musk and company didn't become billionaires by making a company that made a billion dollars, they became billionaires by starting a public corporation that became worth billions and billions. It's been getting harder and harder to do that ever since not least to laws passed after the Enron scandal, the 2008 crisis and such. Every social media company that had the possibility of going public got bought by Facebook or Microsoft.
