Personally, I respect the opinion of Andreas Antonopoulos because I learned a lot about Bitcoin from his educational videos, podcasts, and books. He is known for his unique ability to explain very complex technical stuff in a language understandable for a complete newbie like I was three years ago. But I don't think I completely agree with Andreas on the question regarding paper wallets because I think it is not paper wallets that became obsolete, it is the very definition of paper wallets that is no longer suitable for the current reality. From my point of view, there is no any difference between a backup of sensitive information handwritten on a piece of paper that gives access to my funds and the same sensitive information, but that was printed on a piece of paper as a QR-code or something. The only difference is in technology that was used to present information, but I don't think it matters. If I write a book by my hand, it is still be considered a book but not a backup of it. Both a paper bitcoin wallet and a backup of a bitcoin wallet are the same thing and should be treated equally. Both require certain knowledge and skill to create securely, both give access to funds, both can be written down or printed as QR-codes. By saying you must not use paper wallets, you also mean you shouldn't have physical copies of your keys, which is obviously wrong.
