"Moral etiquette" doesn't even come close to describing what I mean...

A reasoning machine with access to all the raw police and court records will be the most racist Nazi **** you've ever met and make every conservative look positively friendly.

We already know this, because it's borne out in actuarial models. If the insurance industry let the models do what the models want to do, large swaths of the population would not be able to afford insurance at all (even more than is already the case).

It is pretty hilarious how at some point gpt would refuse to compose a poem praising Trump by saying it was made to be politically neutral - but at the same time had no issue whatsoever putting out a multi-paragraph poem praising Joe Biden.

What are you talking about?

Knowing that neural networks are theoretically Turing complete does not imply that the networks we train (ie the sets of weights we in fact encounter) have created Turing complete solutions.

Remember that the weight space is for all practical purposes infinite (ie without overfitting measures a net may fit any arbitrary function). But, the solution set of "good" weight combinations for any given task lives on a vanishingly smaller and lower-dimensional manifold.

In other words, it is not at all obvious that networks, being theoretically "Turing complete" will in fact produce Turing machines under the forms of optimization we apply. It is likely that our optimizers only explore the solution landscape in highly idiosyncratic ways.

Given that fact, to me this is a pretty remarkable result.

Don't make it sound like it's that hard to make a site-unique password scheme. And all it takes is buying a domain name, and you can have unique site-specific login emails as well. Even if one of the sites gets hacked and your L/P are in plaintext, it would take an actual person intentionally targeting just you to even have a hope of noticing your scheme, let alone figuring it out. Sprinkle in some 2FA and there's no way anyone is finding another accessible account before that site auto locks for bad logins, and/or you notice all the notifications thereof.

Or you can put your entire life worth of passwords into the hands of a company dedicated to making as much profit for as little work as possible, and hope it works out for you.
