Yep exactly this is what I was thinking the whole time. If you don’t set up activation lock, you’re taking a huge risk. I do agree that maybe they should be more insistent that you set it up (especially since it’s less obvious why you need to with a Mac vs an iPhone).
Nothing I have done in my career has given me even close to the benefit I got from learning Haskell. I don’t get to use it professionally, but the patterns I learned to recognize in Haskell are everywhere.
