Then on top of that there's the slop that comes from the university's PR department, where they turn "New possibly-interesting lab result in surface chemistry" into "Trillion dollar battery technology launched".

(Now that I think about it, I haven't seen much battery hype lately. The battery hype people may have pivoted to AI. Lots of stuff is going on in batteries, but mostly by billion-dollar companies in China quietly building plants and mostly shutting up about what's going on inside.)
