Google has really been sucking at research purposes for years. All it seems to give you is sponsored spam and AI-generated webpages.

A few months ago I tried to look up info on a long-closed hospital that my grandmother used to work at. No matter how many times I modified the search by putting the hospital's name in quotes, Google would keep returning nothing but links to other local hospitals and clinics, and pharma company websites. It used to be really easy to find obscure shit and personally curated sites, but it's gotten difficult to impossible to find anything now. Either those sites don't exist anymore or Google pretends they're not there.
