Well it is one thing to automate a repetitive task in your job, and quite another to eliminate entire professions.

No it is not. That is literally how those jobs are eliminated. 30 years ago CAD came out and helped to automate drafting tasks to the point that a team of 20 drafters turned into 1 or 2 drafters and eventually turned into engineers drafting their own drawings.

What you call “menial bullshit” is the entire livelihood and profession of quite a few people, speaking of taxis for one.

Congratulations, despite you wanting to look at it with rose coloured glasses, that does not change the fact that it is objectively menial bullshit.

What are all these people going to do when taxi driving is relegated to robots?

Find other entry level jobs. If we eliminate *all * entry level jobs through automation, then we will need to implement some form of basic income as there will not be enough useful work for everyone to do. That would be a great problem to have.

Will the state have enough cash to support them and help them upskill or whatever is needed to survive and prosper?

Yes, the state has access to literally all of the profits from automation via taxes and redistribution.

A technological utopia is a promise from the 1950s. Hasn’t been realized yet. Isn’t on the horizon anytime soon. Careful that in dreaming up utopias we don’t build dystopias.

Oh wow, you're saying that if human beings can't create something in 70 years, then that means it's impossible and we'll never create it?

Again, the only way to get to a utopia is to have all of the pieces in place, which necessitates a lot of automation and much more advanced technology than we already have. We're only barely at the point where we can start to practice biology and medicine in a meaningful way, and that's only because computers completely eliminated the former profession of computer.

Be careful that you don't keep yourself stuck in our current dystopia out of fear of change.
