Continuity mistake: Before the lizard assaults Gwen in the lab, she has her hands on the device with nothing else, but suddenly has the spray bottle and the lighter.
Continuity mistake: When Spider-Man is launched against the library, when he lies on the floor the type of books next to him change between shots.
Answer: Connors believes that humans are too weak and flawed, and that if he transforms them all, he'll create a better, smarter and more powerful species. Presumably, given his motivations are to "improve" humanity, he also believes that society itself will also evolve into something "better" (even possibly utopian) once everyone has transformed. As for all the minutiae like what people will eat, hobbies, etc.? I don't think Connors has really thought about that. His obsession is very surface level, and basically starts and ends at "If I turn people into powerful hybrid beings, everything will be better!" Realistically? There'd probably just be a lot of panic and chaos, a lot of people might hurt or kill themselves when they realise they've changed into another species, and society would probably collapse for a while before slowly rebuilding itself over the course of years.
