Yeah, no. It's the same theme Marx recognized some 150 years ago:
John Stuart Mill says in his “Principles of Political Economy":
“It is questionable if all the mechanical inventions yet made have lightened the day’s toil of any human being.”
That is, however, by no means the aim of the capitalistic application of machinery. Like every other increase in the productiveness of labour, machinery is intended to cheapen commodities, and, by shortening that portion of the working-day, in which the labourer works for himself, to lengthen the other portion that he gives, without an equivalent, to the capitalist. In short, it is a means for producing surplus-value.
[Capital, IV.15]
