Ask HN: Ongoing education and Masters programs focused on AI

I'm in a senior technical role with many years of experience delivering enterprise systems and startup solutions. I am trying to cut through the chatter of the capabilities of LLMs and other modern AI. I have noticed several online learning options that are credentialed and in some circles I believe this is still important.

Everyone from Stanford to Georgia Tech is offering certifications and Masters degrees.

What is HN's opinion on the validity and usefulness of these courses over less 'credentialed' sources like YouTube, HN, PluralSight, etc?
