The original Westworld thread is pretty long, and for shows like this (with a lot of interest and speculation) we often do individual season threads so people can read along without having to worry too much about putting everything in spoiler tags.
Addendum, though: would like to exclude random theories we all read elsewhere on the Internet from this thread. They potentially ruined a lot of last season. I realize most of them were not spoilers because people didn't know if they were true, but sometimes when the entire Internet is crowdsourcing a theory, it can be so good that it might as well be a spoiler.
On the other hand, speculation is fun! But I think it makes more sense for it to be done in smaller groups, with the users here. I think theorizing with friends is a lot of fun but theorizing with the entire Internet brain is less so.
Anyway, have at it! I'm kinda swamped right now but will try to get some general thoughts up about the season 2 premiere later.
