When the first machine was invented, people thought workers could take it easy. But what happened? More factories appeared, the workload increased, and capitalists were all smiles, while workers still had to toil away. When computers first came out, we thought we could say goodbye to pen and paper. But what happened? Now, we can't even go to the bathroom without taking our laptops, afraid of missing an email. And don't even get me started on phones—we thought they would broaden our horizons, but our view has shrunk to the size of a screen. Many jobs are now completed with AI assistance, and tasks that used to take three days now have to be done in one. Keynes once said that by the end of the 20th century, technological advancement would reduce the average workweek to 15 hours, but maybe only the Nordic countries have achieved that.
I think that AI alone will not really take over any jobs. We currently only use it as you said, AI assistance. It has basically become a useful tool that helps us and makes the job easier. But the job still remains as is.
In the future when we have even newer technologies then perhaps a mix of those technologies will take over old jobs. But right now only humans are versatile enough to get any and all facets of a job done. That is not something AI can do.
