Credentials are a way to externalize trust. The trend with AI is to further erode trust. There will be a reaction against this eventually, and it's likely that more mechanisms to externalize trust will be found, not that they will become unimportant.

I think the problem is, compare credentials with reputation. A programmer who possesses no credentials might create "good" software that is validated as "good" even by those possessing credentials. However, a person with credentials related to programming, might produce malicious software that betrays the "trust" of the credential. Thus, just like the fallacy of the labor theory of value, credentials do not inherently relate to the production of heritable wealth. AI shines a light on this disconnect, and that actually the involuntary nature of certain credentials (as opposed perhaps to credentials themselves) creates certain classical impediments to the creation of wealth.

Thus, maybe credentials might be thought to be "necessary but insufficient" for achieving certain goals or validating trust. But even in this above example, the credential was not even necessary for the production of "good" software. AI of course simply exposes this truth as it gives more direct access to skills and knowledge to the average person: the (involuntary) credential was never necessary for doing some of these things, and we are able to remove the necessity entirely in some cases.
