The useful core idea of "shift left" is early collaboration between development and various testing functions.

But, again, that was being done in many organizations (and for sure, in most successful chip companies) well before anything was ever labeled agile.

I agree that it was done by many organizations before “agile” but that’s true of all agile practices. Agile is a philosophy and a collection of tools. None of the tools are new though.

Which is what, honestly, makes the term essentially meaningless.

To the extent that parts of agile are and have always been "best practices" we already had a term for those.
