It's not really hard to see... spend your whole life defining yourself around what you do that others can't or won't, then an algorithm comes along which can do a lot of the same. Directly threatens the ego, understandings around self-image and self-worth, as well as future financial prospects (perceived). Along with a heavy dose of change scary, change bad.

Personally, I think the solution is to avoid building your self-image around material things, and to welcome and embrace new tools which always bring new opportunities, but I can see why the polar opposite is a natural reaction for many.
