It is, actually. People have infinite wants. Productivity increases lead to lower prices in the sector where the productivity increases happened.
Lower prices lead people to spend the difference on something else ("private taxi for my burrito" is the meme example.)
Spending the money on something else creates the other jobs.
This is why we have 150 years of unemployment and labor force participation data, and the peaks and valleys have zero correlation with internal-combustion, electrification, or IT.
Now....are those other jobs ones represented by a 100 year old union that is used to having the entire US economy in stranglehold?
No, probably not. The overall economy gets vastly wealthier.
But, if you are a 50 year old longshoreman, that's small comfort.
