I have noticed that, too. Part if it is that they may be trying to improve their AI, and ironically that makes it worse at first. Maybe the old AI is no longer in use. Neural networks are tricky.interwebz.....I do random dowsing searches and go on image hunts..... see where the weird algorithms take me..... so I am not entirely sure.....been a thing with me for some time, kind of my own game I play with when on computer
you could do a reverse image search, that is useful, and sometimes if "godle" cooperates there are interesting cross-references to follow up
but it has gotten weird over the past decade, yielding more commercial schlock than nuggets as the whole thing centralizes.
