I would be surprised if there weren't papers arguing that youthful recklessness morphing into adult conservatism is a learning strategy favored by natural selection.
To continue to experience novelty, you have to find new patterns, not just new things that fit patterns you know.
Staying in tech has been easier as so much within it is changing.
I'm not saying there aren't definite drawbacks but when considered like "it just is what it is" I can at least see some of the benefits. There's something to be said for in-depth knowledge and exploration on a specific field or topic but there's also something to be said for having a breadth of experiences and skills. In many ways it can make you more adaptable and when you find yourself needing to draw on skills and experiences, it's a lot easier when you're at least familiar with them even if you're not an expert.
Like I'm not a skilled electrical engineer but I've wired up a house and tied in a breaker panel as part of a job I held for a short time years ago. So when I need to replace a fixture or a garbage disposal, where friends might hire someone and pay several hundred dollars to have it done, I can do some quick research and leverage my limited experience to do it myself. For bigger jobs I still hire someone but that's just how it goes.
Or the fact that I'm not a software developer or network engineer but when I need to set something up on my home network or troubleshoot something at work, I at least understand basic concepts just from screwing with computers for so long and I can usually sort things out with some research or assistance. Most other friends and acquaintances outside the field would just look at something like setting up a home subnetwork and file server for IP cam surveillance as beyond their abilities. My general familiarity means I can sort it out with a bit of trial and effort.
Same goes for just about anything. If I've tinkered with something related as part of my neverending quest for novelty, I don't need to start from scratch every time I need to do something similar. And when a task or endeavor is outside of my abilities, those people who have dedicated themselves to a deeper exploration of a skill or field can come in and make use of their way of doing things. Can't run the economy on just tinkerers, obviously.
