I'm not indicating that computers have free will. But you have
  differences in temperature, humidity, usage patterns.

  The longer you use a computer, the less alike it is to any other
  computer on the planet earth.

  I'm thinking on the level of flip/flop states though. On a far
  away zoom, yes, they can be considered identical.

  But what packets they are receiving from the 'net?
  Key presses from operator? Memory states?

  I've worked with computers since I got my first one in 1983
  (Tandy Coco2) and never stopped. The love for computers and
  their workings has stayed with me since I was 11 years old.

  But they really *do* exhibit 'personality traits' of some kind
  over long periods of ownership. Most bugs can eventually be
  tracked down, but the logic you have to use can be VERY strange.

  First encounter with a weird situation was a piece of commercial
  Foxpro based software back in... gosh, 1992.

  They couldn't figure out why this software was locking up in the
  same place, but NOT every time. It appears consistent yet also
  random.

  The software company was no use. The computer company was no
  use. They had 5 technicians before me and THEY couldn't figure
  it out. Wasted weeks on this critical piece of software that
  JUST stopped working reliably.

  I was one of their carpet cleaners. [it was a carpet cleaning
  company]. But I knew computers and helped people on the side for
  cash.

  What did it turn out to be?

  Bad video card. Hercules graphic card developed a hot spot.

  Replaced the card, and $12 later (and paying me $100 for the
  troubleshooting/repair) they were saved... after wasting a lot
  more money on others.
