The current Thinking Machines is a software firm, and Daniel Hillis is no longer amongst the top management. The name lives on, but the business of designing, building, and selling exotic supercomputers is kaput.

Not an uncommon story in the computer business. Even Control Data Corporation still exists in a transmogrified form, although their mainframe business went up in smoke ages ago.

MasPar still exists as a software company, they changed the name however.
