In a conversation with Phaedrus, Socrates worries that writing could impair human memory, as people depend on written words instead of recalling information. [0]

The question is will we one day have tools so powerful, that the human is vestigial, and tool (without human) is just as powerful and cheaper than tool (+ human)?
AI might replace it.
Writing "replaced" some forms of intellectual effort.
And it's yet to be seen how AI will play out.
I find that it is true that new mediums and new technologies for language have a numbing effect on certain senses and an amplification of others.
Writing is beneficial in one regard but does have an impact on memory. Epic poems of great length were memorized in their entirety, a skill that would be a lot easier to develop in a world without writing.
Not without a solid result establishing so. But good luck with this, you'd probably need to compare our world with internet and a similar enough world but without it, which does not exist.
In any case, internet can't be reduced to "tiktok et al"
In already developed countries the Flynn effect seems to be reversing, ie IQ is leveling off or even dropping.
It's basically impossible to improve an adult's g-factor, for example. For children, things like nutrition and hygiene (e.g. no parasites) play a big role. But the kinds of things a human learns or tools they use doesn't significantly affect G-factor.
Many other mass produced products we buy today are clearly lower quality than ones crafted by artisans 50 years ago, and yet they do what we need them to do at a fraction of the cost.
I think that's a sweeping generalization. For example, it's much better to have a bunch of food that's mostly garbage than to have a famine where all food is super high quality. There were points in history where this choice was made (obviously unconsciously because the choice is too obvious to even think about). Other examples abound.
Technology often makes things much cheaper while reducing quality. Sometimes that's bad, sometimes it's great.
Like any idea about squishy human brains and its products it remains to be seen and can’t be as easily proven as for example research in Physics.
I would say current research has a probability of 50% of being correct at best.

This coupled with an broad interest in just about anything means I can often help people far outside my specific field, usually rather swiftly as well.
Taking into account that such blunt statements always hide a lot of nuances, this seems to capture the reality.
Qanon was purely a creation of the internet. Now go take a look at how many people believe one, many or all of the various Qanon alternative facts.
They don't prove that it makes people dumber. You have to quantify and qualify people and to define "dumb".
Maybe people are not actually dumber because of the internet, but the internet is very good at spreading ideas, including incredibly dumb ones, especially (because of how human beings work) those likely to cause feeling of outrage.
Maybe people are not dumber, just too defenseless against the scale of bullshit they are faced with because of the internet. Maybe internet is an incredibly good tool, but strongly requires good learning / training of critical thinking and there's not enough of this yet.
It's hard to argue that nowadays people believe more crazy stuff than before the internet was invented. (It's very easy, of course, to claim this, as many like to do.)
