Just got back from Buenos Aires for https://btcpp.dev/conf/ba24 . Just as high quality of an event as the one in Mexico, @niftynei did a great job organizing. Presentations were solid, mostly about engineering using Lightning for real world scenarios. It was great to get a concrete sense of what the south American community of Bitcoin engineers are like, I was impressed, a lot of very competent people. Bitcoin conferences used to mainly consist of dreamers .. but nowadays I see people that are both normal, and also seem like they could get shit done.
I also finally got to experience the famous "bitcoin LARP" in person (I have some things to say about that, will probably write a separate note).
bitcoin devs: get shit done TM
