The part of the article that mentioned Bell Labs’ philosophy for choosing research problems reminds me of Richard Hamming’s famous “You and Your Research” talk, where Hamming talked about the importance of working on important problems, and how he asked his colleagues about the importance of their problems.
Come to think of it, part of the reason why Xerox PARC and Bell Labs are so renowned is because of the importance of the problems they worked on. Transitors, Unix, Smalltalk, the Xerox Alto, GUIs, word processing, Ethernet, the list goes on.
