No, the other guy is just wrong. Capital and labor are complements. If one is plentiful (capital) and the other scarce (labor) then the scarce one gets bid up.

You pay the one technician $200k instead of $80 because that technician has an outside option that will pay him $199k. He has that outside option because everyone is automating their warehouses and factories and stuff, and so in aggregate we basically wind up with 6 times as many warehouses and factories each employing 1 person.

It's a little more nuanced. There is not infinite demand for warehouses. So some of what happens is an $80k/year warehouse worker becomes a medical technician making $90k/year providing non-automatable services to the warehouse guy making $200k/year -- but the general story is everyone's wages go up. And history bears that out.
