It's dangerous to outsource our critical thinking to computers

"The engineered environments of Facebook, Google and the rest have increasingly discouraged us from engaging in an intellectually meaningful way"

I fail to understand if it's their duty to inculcate critical thinking in all of us . While reading any article on websites I try to fact check while searching on google , I dont believe any random article getting viral. Yes I agree there is lot of content online which might not be correct but outsourcing critical thinking to computers using correct resources might not be a bad idea depending on way it is done
