Anyone on Google reading this -- please either cut that out, or include css placeholders for content you expect your JS to load.
Both waiting longer for content to load and having to go back from clicking the wrong thing detract from the raison d'etre of fast and relevant search.
This catches me out regularly. I would not be surprised if a team at Google implemented this and immediately saw “increased engagement” from users in an AB test, so they locked it in permanently and considered it case closed, the science is in.
Scientism at its worst.
I think it was something like "other people also search for..." thing which poped up unexepectedly.
