I kinda wish people with no background in machine learning would stop misusing their scientific cred to spread alarmism.
Every time an AI playing an optimisation game with an extremely select and rarefied real-world dataset does something remotely unexpected, there's always a crowd of people asking whether this means the machines have risen. Every time they completely disregard the fact that this is a program with a very narrowly-defined purpose, goal condition, and inputs/outputs, which has neither access nor ability to rewrite itself, solving a single task that was externally defined for it, using a limited amount of mathematical abstractions that may or may not be suited to the given data.
Yes, interpretability is an issue for some machine learning methods (though not for all of them - Bayesian methods and tree-based methods are perfectly interpretable and quite powerful) but it's more of a debugging issue than a machines-plotting-against-us issue. Of course, one might say that one is suspicious of anything non-interpretable, but then you might as well suspect that your aunt is plotting your demise, since she's even less interpretable than a neural network classifier. This is actually more probable to boot.
Of course, machine learning has a huge potential for misuse, and has already been misused - by people, as a tool. I'm not saying everybody should be happy about it, I'm just saying that when you suspect ML researchers and techs of knowingly or unwittingly being close to general-purpose AI, you're giving us too much credit.
Strangely enough, I've never heard an actual machine learning researcher voice the same sort of concerns as people from other fields. Of course, that Stephen Hawking says something shouldn't be dismissed out of hand, but he's an astrophysicist. If someone like Andrew Ng said the same, that would be a relevant authority, but Hawking and Musk (whose background is in economics and materials science, and who is primarily an enterpreneur and not a researcher) unfortunately aren't.
In light of previous disagreements, I would like to say that I in no way intend to be dismissive or condescending and I apologize preemptively if my tone comes off wrong - I always have problems with gauging this sort of thing in text, so yeah. Sorry. This is just relevant to my experience, even though I by no means claim to be Andrew Ng or whatever.
Eh, I got ninja'd by everybody, but it would be a shame to let so much smartphone typing go to waste.
