Indeed, I thought that "decades old" sounds like an underestimate there: Socrates is said to have criticized writing for letting people to not train their memory, so that would be millennia by now. Though of course it is possible that the article's author would not agree with that, and would have a beef with more easily searchable content only, like the people who criticized tables of contents. I do not mean that they were all wrong though: probably the degree to which knowledge is outsourced matters, maybe some transitions were more worthwhile than others, and possibly something was indeed lost with those.

Sorry, kids lack the foundational ability to remember, reason, imagine because their phones cauterize their basic intelligence foundations in sharp wave ripples: navigation, adventurous short-cuts, vicarious trial and error, these are the basis for memory consolidation. And we build this developmentally until we are 16 or so. Once we offload this dev to phones, we are essentially unintelligent buffoon, lacking the basis for knowledge. The kids are DOA.
