For the most part I agree with what you've said here but also 50 years ago a person had exponentially more value within the economy because technology didn't exist that could do their job. I already went over that in detail in the OP so I'll leave it at that.

It might logically seem like a farmer or a blacksmith provides more value to society than a youtube streamer, but that's simply not the case. The blacksmith profession doesn't even really exist anymore because of factory production. It doesn't exist because it has very little value within the current environment. So you might not like it but these entertainment jobs are gaining value within the attention economy, while creating actual products and providing needed services will continue to be valued less and less and trend towards a state of decline.

At the end of the day automation combined with increasing population ensures that there are always going to be a lot more people than their are jobs. All the new jobs will be linked to the entertainment industry as we fully automate the base layer of the economy.
