That's not what "disruptive technology" means though. There's a very specific book [1] that described a specific dynamic to new technology innovations, and you lose a lot of precision by generifying the term.
In the colloquial sense, most workers jobs' get disrupted by garden variety financial innovation anyway. It doesn't really matter whether your job can be done by machine, the PE firm or corporate finance types will just lay you off, leave your job undone, and boost margins so they can unload the stock before customers realize they're not getting anything for their money.
I don't think that we should dogmatically stick to one specific definition for such a generic term like "disruptive technology," especially considering that's not even the first usage of the term -- https://en.wikipedia.org/wiki/Disruptive_innovation
The original paper linked to there describes the same dynamic - innovations originating outside the industry which incumbents can't compete with because they have a different set of customers.
