For most people in crypto he is right.
For some very careful and technical trained and social aware people, the paper wallet style might still be an option (Also i recommend steel engraved word lists)
Remember, we have a majority of users with few computer skills. They are in for the craze and the moonshots and meme coins.
Whatever instruction they follow, they have no idea what is safe. They ll likely loose their coins when dealing with paper wallets.
Regardless of the audience, claiming that paper wallets are obsolete is pretty misleading. In fact it is more misleading if the audience is at beginners level or doesn't understand much. They should be educated on why and when a paper wallet is insecure or doesn't provide the functionality that you would want (single private key compared to HD wallets). And more importantly they should be told about what they can do to improve that.
