I was having a conversation with someone about whether or not robotics and AI will cause problems by eliminating jobs. They said:
"People worried about joblessness when we started to mechanize farms, their worries never panned out, therefore your worries now are misplaced."
Or to use another example:
"The last big asteroid that came close to earth didn't crash into us, therefore we'll never be hit by one ever."
Without any justification as to why the two situations are similar this line of thinking seems like it is a fallacy. If so, what is the name for it? If not is there any other word or term that describes the line of thinking?
