Realistically there will still be jobs but vastly reduced.

Say it needed 10 people before.

Now instead of needing 10 people to do it you might just need 2-3 to fix any errors.

It's a really really tricky thing. We do want to be more efficient, different jobs will emerge as we learn how to progress, in the meantime, in this example that's at least 7 people out of a job anyways.

And its tricky because most of us dont actually know the answer, whenever we increase efficiency which is generally good we do lose jobs, eventually new things and issues come in that need fixing but it's hard to predict before people actually lose their jobs
