When Plato complains about writing diminishing our faculties for memorizing things, it's sometimes treated as an example of how we've always pointlessly worried about these things, but he was absolutely correct and the transition from an oral culture to a written culture has absolutely demolished those capabilities.
Writing as a technology ended up having strong upsides that mostly made up for that (in particular our ability to communicate across distances and time, to read Plato's concerns without 100 generations of Chinese whispers), but it was a trade-off, as most technologies tend to be.
How else could mind-virus like philosophy or religion or science or political legitimacy transit highly-variable humans for generations?
Religious organizations, governments, corporations all far outlive their founders and maintainers. Heroes at best only stretch or squeeze the dogma or methodology to grow the organization by better fitting to the culture.
And because organizations accumulate control over resources, individuals can have little effect outside them.
We are disposable by design.
Not my idea though, greater minds than I have talked about this a lot: Neil Postman, Lewis Mumford, etc..
