For my second point -- I definitely didn't mean optimization that way. I guess the word I meant to use was "targeted", as in "targeted for multi-core" but I see your point and respect it fully.
I'm thrilled and deeply, deeply honored to have had this time with you, Dr. Kay. Thank you so much again. If you're ever in the Bay Area on the first Saturday of the month and feel inclined to stop briefly by the 2020 group meeting (which is an attempt at a replacement for the Future of Programming Workshops that used to take place at Strange Loop), we would be over the moon. You can reach out to Jonathan Edwards if you need the details.
