When tools increase a worker's efficiency, it's rare that the job is lost. It's much more common that the demand for that job changes to take advantage of the productivity growth.
This is why the concerns from Keynes and Russel about people having nothing to do as machines automated away more work ended up being unfounded.
We fill the time... with more work.
And workers that can't use these tools to increase their productivity will need to be retrained or moved out of the field. That is a genuine concern, but this friction is literally called the "natural rate of unemployment" and happens all the time. The only surprise is we expected knowledge work to be more inoculated from this than it turns out to be.
