People have other dreams, and have written about them in science fiction. But science fiction can just handwave away resource problems that exist in real life so that the plot can happen.
Just as the popular "grey goo" nanomachine disaster can easily be shown to be impossible due to resource imbalances and energy shortages, AI recursive self improvements rapidly slows down due to problems with complexity, training data and compute availability (whether due to actual processors or just due to energy demands).

Depends on specifics and how dramatic they're being, given that "mold infestation" can come in grey.
whether or not the singularity would be best thought of as science fiction, it was not presented as such, and has not been taken as such by a great number of people, and has formed the basis of a lot of opinions as to how things will pan out.
It is these opinions that make the conclusion the parent poster supposed should be obvious to everyone not obvious to so many.
The problem is in cases of the singularity it's being treated like reality rather than fiction
