Humanity has a history of regarding people as tools, but I'm not sure what you're referencing as the track record of failing to realize that tools are people.
at some point, some of the (current def'n of) people were not considered people. so I think you should reconsider your point. The argument is on the distinction itself.
Humanity has a pretty extensive track record of making that declaration wrongly.
