It would be nice to see the Go server that powers Parse.com's production servers. I recall in Gophergon 2015 there was a presentation on how they migrated from Ruby to Go. https://gophercon.com/talks/rebuilding-parse/
If you want to make Ruby better, change the IO subsystem. Look towards Go and fork the language. It's the only path I see. Btw, I spent 8 years writing Ruby and would love to see that happen.
socialize :) go have fun, get outside, talk to people and listen too.
follow your interests - find a group of people who share the same ones. Ie. if you like running.. join a running club.. you'll meet people for sure. Also, if you work in the Bay Area.. have you thought about moving? I feel its very male dominated and one-dimensional, .. move! and expand your horizons outside of software. There is nothing wrong with being an introvert who likes their time and spends time thinking. But, I bet you'll surprise yourself the day you do meet your soul mate and how motivated you will be to do stuff, and bounce between intro/extro-vert. Do animals have these terms? I don't believe in putting ourselves in these boxes.
