         | Really doubt it. This "Thinking Machines" seems like an on-
         | trend SV AI software startup, that "Thinking Machines" was a
         | Massachusetts-based hardware company that went bankrupt 30
         | years ago (and whatever's left is Oracle). That "Thinking
         | Machines" people are retiring by now.
         | 
         | I wonder if Sun/Oracle let the trademark lapse, because if it's
         | still active I'd imagine this startup's gonna get sued.

               | The formation etymology (whether from tin or

               | least the 13th century for an itinerant mender of pots,
               | the Travellers. By the 16th century it became a slur for
               | Travellers.
               | 
               | The verb to tinker doesn't appear until the mid-17th
               | century, first meaning to work as a tinker and only later
               | coming to mean what you're familiar with.
               | 
               | So while the root word's sound-shape is debated, the
               | order of senses is clear: the Traveller sense comes
               | first, the modern "casual repair" sense comes later and
               | was derived from it. This is the etymological order given
