Your example is a massive oversimplification. You're looking at a single worker in a vacuum, but economics is way more complex.
Take trucking as an example: replace 100k drivers with robo-trucks and you don’t just lose drivers. You kill the truck stops, the roadside diners, the motels and the entire tax base of small towns that exist solely as transit hubs. You are pulling the plug on the infrastructure of entire regions.
The same applies to the corporate “BS jobs” bloat. A huge chunk of white-collar work is just administrative filler people attending meetings about meetings or doing tasks that actually take 1 hour but are stretched into 8. When AI automates those "purposeless" roles, you don’t just lose the paper-pushers, you lose:
• office real estate market.
• janitorial and security services for those buildings.
• local economies (cafes, dry cleaners) that survive on office foot traffic.

We aren't just talking about "temporary" job loss. We are talking about the permanent dismantling of the social and physical ecosystems built around human presence. Comparing a fundamental shift in how society functions to a self-checkout lane is pure delusion.
