20 years of Google Scholar

Yes, Google deserves to be distrusted and avoided as a whole, but Google Scholar is a genuinely net good for humanity.

I have similar feeing for Gmail (it's effective anti spam engine), google maps and google docs (which pioneered shared docs. It feels outdated on many fronts now, but it was a pioneer).

anti-spam is only an issue if people dump their email anywhere. I usually register my mail on webpages as first.last+webpage@mail.com and once they would spam this mail, it gets blacklisted.

I literally get only 1-3 real spam mails per month without any filter.
