When you watch this report of the invention of a new robot in tentacle form, your instinctive reaction will fall into three camps. Some people will go “ooooh” at the possibilities of this new technology. Some people will go “ewwww” at what is a very odd-looking thing, which is not at all conventional in its behaviour.
And there is a third group, who will find themselves crossing their legs.
I’m in that group.
I did actually write a short story a while back with an invading caterpillar-like creature that moved by eversion, which I might post up here for comparison…
