Funny coincidence. Yesterday I watched the talk by SPJ about Lenses and it finally clicked for me :-)

Maybe someone has an actual public link to this with no login needed?

This is such a good presentation. The story it tells of the derivation of the type is ahistorical, but it makes a lot of sense. If you are looking for an intuition of how the types work, it's just fantastic.

Thank you so much, watching that talk finally made it click for me as well!
