If you asked them, they probably think Google is the internet, and if you have to find anything, you have to go to Google to find it.
I'll admit I have no proof of this, but I've found, generally that the non-technical individuals I know, have incredible poor working knowledge of the internet. I take as my primary evidence though the masses vulnerability to really stupid and easily caught scams, spoof websites, click bait, and spam emails.
As a technical user, I'm constantly baffled that people fall for this crap. So if people really are that incomprehensibly ignorant, I'll bet they don't' even really know what a google is and why they use other than it's all they know and they'd be lost without it.
If the general public can't figure out no one is going to hand them a million bucks from nigeria, how the hell can they figure out you don't have to use Google?
I use DDG btw. I find their results fantastically good. So good that I can't even use google. The spam, the adds, the poor results. I cant' take it. I also can't handle that google returns different results on different computers.
I get the same results on DDG every time i make the same search. I've gotten lazy and started performing searches for things instead of typing in the address because it's consistent and faster.
