And one day we'll all be obsolete, implying we won't be able to show our value through our work.

Brave New World. Ideal for a certain social class: the alphas.

Food, material goods, and services are cheaper and more plentiful than they have ever been in human history. Add to that: jobs are easier to discover, self-teach, and contact than they have ever been in human history. For the poor as well as the rich.

The main thing people get unhappy about is wealth disparity ie., how much MORE the rich have than the poor. That even today's poor have a rectangle that's effectively a magic portal to the entire world's knowledge and population is not satisfying to you when you read headlines about Bezos' mansions, right? Allow me to humbly suggest to you that if the dominant emotion of your worldview is envy, you would not have been any happier in decades past.

Nice narrative. Yes, poors are better in a materialistic way. Now, what about their freedom? Is that also getting better? You might recall the magic rectangle from Farenheit 451...

Don't strain your back moving those goal posts. ;)
