The suggestion was that workers (“we”) should seek to automate processes that workers prefer not to perform.
Your objection was that if such automation were possible to achieve and to implement, then they would have already done so.
Processes of production, and the utilization and development of machinery implicated in production, is determined by business owners, not by workers.
Business owners are bound by the profit motive, not by a motive to improve the experience of workers.
Any activity or objective not supported by the profit motive is simply discarded, under our current systems.
The meaningful suggestion is that workers (“we”) should seek to automate processes that workers prefer not to perform, even if business owners (“they”) have no motive for doing so.
