That's a reasonable problem to have, but I think it is more created by your limiting beliefs than anything else.

My work environment makes it impossible for people to casually talk even when not much is going on

Beginning or end of the day? During lunch? Even if you shoot the shit with just one person every day, that's one more than you seem to be doing right now.

but there’s not really anyone to talk to during those times other than maybe people MUCH younger than me (like around 10 years younger) and I feel even more uncomfortable talking to them since I don’t want to seem like a creep or that older guy trying to be cool with the kids.

This is a symptom of being chronically online. Older people talk to younger people all the time. Hell, older people date younger people all the time. People like to talk to people, and if there are people around, its not weird to talk to them regardless of their age. As someone approaching my mid-thirties, one of my favorite ways to talk to college-aged kids is to lean into our age difference and just be like "so what are you kids these days all into?" And if you are worried about being a creep, you can lean into that, too "Hey, I hope I'm not just being a total creep right now, but I was kinda bored and wanted to see what you kids are up to."

Finally, you can make small talk with literally anyone who comes into your proximity during the day. People waiting for the bus with you, people just chillin in the park, grocery store checkout clerks. For example, say you are checking out at the grocery store.

"Hey, how's it going?"

I'm doing good. You?

^ this is the stock response that is just acknowledging you exist. Follow up with something that indicates that you actually give a shit.

"Day going good so far?"
