Is there a name for this specific concept? Where somebody invents something (to do them good) but then that thing turns around and backfires on them?
There’s the phrase “Hoist by their own petard” but not sure if that’s specific enough to inventions, probably not.
I really hope there’s a single word for it out there… more convenient yanno.
There’s probably a German word for the concept that there is a German word for everything.
Hubris. Irony.
Not sure about a name, but:

Weird seeing Stockton Rush on there when most of the other inventors are pre-20th century.
Also not sure about a name, but in Greek mythology, there’s Daedalus. He built a massive maze, which was then used against him to imprison him & his son. Daedalus crafted wings out of feathers & beeswax to escape the island of Crete, but his son Icarus flew too close to the sun. Melting the wax, destroying the wings, and drowning in the sea.
I think Frankensteinian would work based off second definition of Frankenstein from m-w dot com.
2: a monstrous creation especially : a work or agency that ruins its originator
Frankensteinian is the adjective form.
