       | The detail about Hoare sitting in the front row at conferences
       | taking notes on specialized topics (after retiring from Oxford,
       | after a Turing Award, after decades of foundational work) is the
       | part of this piece that will stick with me. There's a certain
       | kind of senior figure who stops learning once they reach
       | eminence. Hoare clearly wasn't that. Meyer's phrase "a
       | combination of pride and humility" nails it.

         | "Once you stop learning, you start dying." Don't know if that
         | quote is actually by Einstein or just attributed to him, but it
         | rings true for me.
         | 
         | Back when I studied philosophy at university, the oldest person
         | in my class was in his seventies and just took random courses
         | in fields that interested him since his retirement 10+ years
         | previously.

         | I like to think that I'd do something similar, as long as I'd
         | have the energy.

         | I think the fact that he wasn't content with learning enough is
         | likely why he did so much amazing stuff. A lot of people would
         | have been content enough to have invented Quicksort, but Hoare
         | went on to make CSP, Hoare Logic, UTP, and a million other
         | amazing things.
         | 
         | I like to think I'm the same way; I haven't won a Turing award
         | yet, and I don't even have a PhD, but I've always been someone
         | who is sort of obsessed with learning new things about software
         | and math. It's basically been the only edge I've had over most
         | of my peers: my willingness to learn new things to try and keep
         | up with trends. Peoples' unwillingness to learn new things has
         | been highlighted recently with AI, but tech has famously always
         | progressed pretty quickly and I've always been terrified of
         | being left behind.
         | 
         | I've grown to really respect lifelong learners. It's very easy
         | (and tempting!) to stop learning after university, but I think
         | it's worth it to never feel like you've learned "enough". My
         | dad is looking to retire soonish, and he's considering re-
         | enrolling in University to get a masters in theoretical physics
         | since he always felt he should have learned that better. I hope
         | I'm the same way when I'm his age.
