The first part if true: Romans did depend on slavery, as did most ancient societies.
I am less convinced that engine jargon is derived from that. Where the terminology is master and slave specifically, yes, but not necessarily in slave societies. Where the terminology is master and something other than slave, I do not think so.
Slave is pretty unambiguous. Master less so. To a middle aged British bloke like myself the strongest association of master that I grew up with was "male school teacher". Master craftsman is also a significant association.
He specifically said "master & slave." IDE master-slave drives are also "derived from slavery" simply because that's what "slave" means, even though the analogy doesn't make much sense (the master drive doesn't control the slave drive and isn't superior to it).
