> The fact that open sourcing something is a good way to find errors in complex systems is a proven fact.
Is your evidence for this anything other than anecdotal? That ESR quote was given after one particular LKML interaction back in the 90's. And sure, sometimes an interaction like that happens. But just as often I've seen an email or bug report to an open-source project get completely lost. Not to mention that 1) new security-related bugs are still introduced into Linux, despite the number of eyeballs looking at them 2) people are still finding security-related bugs in Linux which are over a decade old. (Not to pick on Linux here -- but Linux probably has the most eyeballs, so according to this theory it should have the least bugs.)
Asserting that open-sourcing has always reduced bugs in all software isn't supported by those anecdotes; you'd need to do some sort of actual study comparing various types of development.
> AI isn't magical in that regard. It is a complex system, and experience with such systems, from economics, to climate mechanisms, to software, teaches us that predictions about them, including error detection, risk management and fixing problems, works the better the more people have a chance to look at its internal workings.
What "AI alignment" people are saying is that from a risk management perspective, AI is different. Namely, the fear is that we'll get an AI which is much more intelligent than us -- an AI intelligent enough to 1) gain a technological superiority over us 2) anticipate and counter anything we could try to do to stop it; and that this AI might end up with its own random "paperclip-maximizing" plans, and care no more about us than we care about ants; and that it might come into being before we have any idea how dangerous it is.
The worst think that can happen with a bug that gets into the Linux kernel is you may lose some data, or some other human steals some of your secrets. The worst thing that can happen from an AI alignment catastrophe is the extermination of the human race.
Now, maybe those fears are overblown. Or maybe you're right, that open-sourcing everything would be the best way to avert an AI catastrophe in any case. But to assert it's true, based on some thing a random guy said after a random email discussion 25 years ago, without even bothering to engage with what people actively working in the AI field are saying, certainly is an ideology.
