Wow just looked it up looks like Amazon, Home Depot, Boeing and Apple all use Ruby, my mind is blown. 

Most of the ruby I saw at Amazon was internal tooling, build scripts, that soft of thing. 

No kidding I thought it was all Python, Java, Javascript, C/C++ at the big tech companies. RoR/Ruby is a bit of a first love so it would be super cool to actually use it somewhere.

Yeah, I still run into ruby here and there. Amazon has a TON of ruby internally, believe it or not. I know some other companies that started with RoR and then got big and are still living with some ruby. I don’t see many new projects starting with it these days.

Best Major or Classes to take to be involved in the lightning/bitcoin community?

Thanks I'll make sure to master it :) I mean I guess it makes sense that everyone has their own specialized version of Scrum. Have you seen anyone use Ruby? It was my first language but I still have yet to see any real widespread use of it. Excited to learn Rust :)
