What Should I Go Hunting For

I've been reading through a lot of posts today, and I am seeing a LOT of terms I've never heard of before.....That means I am only aware of the tip of the iceberg.

Could you all list things I should be looking for? For example I read today about some AI app, Spotify, App Containers???? I know the list is endless, but help a girl out please! Can you also explain what the things are?
