Meet up to play a tabletop game?
Go for a hike?
Have a group receive a tech presentation once a quarter?
Lots of options, most just take your time and emails/contacting possibly interested folks.
You could go out to lunch and have a technical chat and the people at the table next to you might chime in with a solution!
When you get enough passionate people and pack them into one location things get interesting for them (networking, friendships etc)... Much of the passion is gone (lots of people see tech as a path to a paycheck), and everyone wants to WFH.
Honest truth is there were always folks without passion in tech.
People have lost the vision and do not understand the soul of the machine is to improve our state of existence not enslave us further.
Fuck 'em. I'm taking the money and doing what makes me feel good (wine, floozies and travel).
can you elaborate?
