And so are all flawed institutions. None of this supports your basic assertion that the risk of misuse or misunderstanding of ML is different in principle from the ways all other techs & processes are subject to misuse or misunderstanding. ‘It’s not auditable’ is not good enough

As a computer scientist, I differentiate between algorithms, which are supposed to be explainable, (even if "how you tweeked the parameters" isn't always), and ML which is heavily data-dependent, in ways that are usually opaque, because data's got lots of latent stuff in it.

We do know the input to any ML model. The problem is that the decision may be correlated to such things we don't know we can detect. But it's not a black box, at least not in the sense that we cannot study it's response to known inputs and compare to expected outputs.
-
But you don't know which of the million outputs matter, how, and if they group and correspond to latent variables that you don't even know to look for because it's not an input by itself. The construct ML is using may not even yet exist in human understanding but be predictive.

That there’s now also a naive or colloquial sense of “algorithm” doesn’t seem fruitful. I understand how ML is opaque but doubt it’s opacity will approach “human”. Hard to believe algorithmic biases will ever be so hidden or profound, though they may be immensely more destructive
-
In other words, I’m sure ML biases will be able to reproduce complex racial prejudice and be discoverable as such. But I sincerely doubt they will opaquely start discovering something like “good art”.

Algorithms are scary even without the ML. Let me tell a story from Japan. We wanted to have internet banking in Japan. The bank had recently decided that this was only going to be possible through a one time password app. The app is available in Google play. But only in Japan.
-
Turns out, our Google play location is still registered in US (even though we have Japanese phones). You don't even see the change country button. We searched a while then deleted our us payment options, only then you could see the change country option. Can change once a year.

I agree with you. ML as it currently exists doesn’t show its work enough to allow human troubleshooting and tinkering if and when society realizes that the effects of some ML decision-making are discriminatory or otherwise detrimental.
