Indeed, people organically spread the meme ("urgent max block size increase required or Bitcoin will stagnate and possibly die") as misinformation, but its origins are probably as disinformation. It's not so much that "humans are flawed", it's more that propaganda and mind control and perception management techniques have gotten quite advanced.
Regardless, they are still flawed. The first thing that one tries to exploit (e.g.) when hacking is the human. Similarly, Bitcoin can't be broken by mathematics nor technology (as of today), and thus the logical step would be to try to exploit the humans.
No matter what everyone says, Bitcoins cannot be brought down. It is liked by many peoples as it is easily and readily tavailable.
That is overly-optimistic at best.
The current price of Bitcoins also suggests that it is growing in a positive directions.
This is not related.
