Among the ones he claims as having come true, a couple of them didn't. Physical media like HDD has greater permanence than SSD, so it isn't going away yet. But his son also used it in gaming consoles, which (it may come as a surprise) are computers.

Also, you can't use whatsapp without a phone number. Several apps and services require a phone number for sign up or 2FA. So that one is bogus too.
