You are coping hard. The guy is right.

Before AI and robotics merge to a point where they are precise and efficient enough (and cheap enough) to tackle the diversity of on-site scenarios of many trades, most OTHER jobs will have been automated.

What you might see is more pre-built houses, for exemple, that are designed to be worked on by robots because they are made to be predictable and fit with AI trained on their models.

But most current buildings and infrastructure haven't been built with robot maintenance in mind. Sometime they're barely built with human access in mind lol. So if we assume infrastructure last 50-100 years depending on the type, that's probably the time scale of trade job relative "safety".

Until AGI obviously. Then anything goes. Either human emancipation from work or slavery to the machine overlords :/
