Brain wallets are good because they are unpredictable, you don't know what the person that made the password was thinking
Nonsense. Human thinking is predictable, their password habits are usually weak/horrible and the adjective simplistic can be used for the majority as well.
Brain wallets can be easily bruteforced.
Indeed.
Humans are really bad at being truly random.
I concur. They're also very bad at probabilities, hence why we get people from time to time worrying about address collision.
Some people are developing fingerprint wallets for online bank accounts and offline shopping.
Replacing passwords with fingerprints is not safer.
Good for paranoids, i can't understand why people is always scared about hackers in 2016, when almost everywhere you can avoid them or just block you wallet?
Stating this, after we've experienced one of the largest 'hacks' (it's debatable what exactly happened, but let's ignore that since discussing it would be off-topic) in the history of Bitcoin, is very ignorant and ridiculous.
