Earlier quoted context omitted.
Anecdotal evidence from 20+ years ago seems like the common argument against Virtual Reality, as well. Technology got better, and cheaper. That puts previously-unattainable goals within reach. Would you argue that a $15/hour McDonald's employee will be cost-competitive with a Big Mac machine nowadays?
Depends on cost of a machine. Plus, McDonalds is a weak even if common example. Many companies push employees go focus on good service or at least sales (esp upselling). Computers still arent as good at that with a good chunk of customers rejecting them outright in such uses. Far as machines, depends on how cost of installation, maintenance, and licensing vs humans it replaces. Varies case by case.
