1/ Second thread on exciting philosophy from outside philosophy departments... https://twitter.com/OwainEvans_UK/status/1326645830963634179

2/ Gerry Sussman. Hofstadter said Gödel invented LISP in proving the incompleteness theorem. Sussman shows the amazing breadth and elegance of LISP ideas. SICP, SICM, How to build robust systems. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjB0_WyhJLtAhUOURUIHZqQBjIQFjACegQIBhAC&url=https%3A%2F%2Fgroups.csail.mit.edu%2Fmac%2Fusers%2Fgjs%2F6.945%2Freadings%2Frobust-systems.pdf&usg=AOvVaw0LGa7VnLjautXwGFTGpdF_

3/ Eric Drexler. Engineering is neglected by philosophy departments (see Sussman also). Engines, Nanosystems, how engineering differs from science, CAIS. Disclosure: he's currently at the FHI (which is part of a phil dept).
