If there was no NES, there would be no industry for PlayStation to expand. And if there was an industry, I doubt Sony would've even bothered putting any money into something that they would've viewed as playing with fire. It was the partnership with Nintendo that led the way to PlayStation being a thing in the first place.
If there was no Atari Pong, there would have been no industry for Nintendo to resurrect, because there wouldn't be one, and Nintendo would still be making cards and toys.
Lets not forget, Nintendo's first foray into home gaming wasn't the NES. It was a pong clone. :P
And also, the NES did not resurrect the gaming industry. The industry was still quite alive on home computers like Commodore 64, ZX Spectrum, and MSX, which were very popular gaming devices in their own right. NES simply re-legitimized standalone game consoles in the US market.
