It's very simple: Lots of people have those jobs, and they either like those jobs or have no confidence that having to find new jobs won't end up as a net loss for them.
The problem isn't that tools make jobs easier, it's that when jobs get easier the benefits accrue to the owners of capital - by erasing jobs - instead of to the people doing the jobs - by allowing them to create the same amount of value for customers/society in less time, improving their standard of living.
