It’s true that they are only as good as their input data, but the same is true if you do your own web searches.
I am sorry to be pedantic, but the correct phrasing would be "I think I know within a second", which seems like a pretty important distinction.
The difference is in rate of generation.
Today, the ratio of good data to slop has dropped. Previously, you couldn't mass produce websites and have content ready to go at a click.
So you had better hit ratios before, and you have worse hit ratios now. The more labour intensive to create content, you lived in a better world.
Hmm, The better the ratio of creating content to verifying content, the better the environment we live in.
