this is a good example of Artificial Intelligence. Stephen
Hawking was likely a little spooked at the progress made when
they fitted him with this new predictive system a couple of
years ago. It was vastly superior to the stuff he used before,
which was circa late 1980s/early 1990s. I could be wrong, but I
think having a system that really *did* seem to know what he was
thinking might have been a tad spooky and started the chain of
events.
