I'm a fan of the Stanford CS380 Seminar class. When I was a younger engineer, before the pandemic, it was more or less open to anyone who wanted to attend. Depending on who else showed up, you could end up having interesting conversations afterwards. https://online.stanford.edu/courses/ee380-colloquium-computer-systems https://online.stanford.edu/courses/ee380-colloquium-compute... I'm sure there's a Berkeley equivalent. So maybe my answer is "check out the local university to see if there are open-to-the-public talks or events." I've found a number of interesting groups on meetup.com, though I find their interface maddening. I suspect there's a lot of hit-or-miss groups, covering a wide range of topics. So... universities and meetup.com.
