Yes, I couldn't resist. I am sorry, but I have maybe seen 2-3 people wearing an Apple watch and never heard about Memories. Apple watch (and Siri) might be a thing in the US but definitely not in Europe or Asia. I feel like Apple have only 2 successful products: Iphone and Macbook. Their biggest success however is creating a cult and closing personal computer hardware (remember IBM/compatible).
And did closed turn out to be an invalid decision? Closed meant control, control meant more security and privacy and avoiding reliance on advertising revenue.
