Oh I know, but there are also a lot of people making claims to expertise they don't have and spreading lies. Some of them are real experts in other fields and so have respect there.
It's generally pretty easy to spot the fakes if you have a basic understanding of the field and are just researching for specific details. Frankly, for the stuff I typically look for, there are surprisingly few fakes to be found. This may change with YT deprecating the down-vote arrow.
I would say critical thinking, learning to distinguish good information from bad is a valuable life skill that is only getting more valuable with time. Something we should try to teach people about from a young age.
