Probably lol most meme/alt crypto is built off the ethereum ecosystem. If eth turned out to be a scam. All of crypto as you know it would crash. 99% of people wouldn't touch crypto again. You may see a correction in the eth price with the new dencun upgrade but it's still going to go up much higher. Vitalik isn't dumb. He's already preparing the eth networks security against quantum technology that hackers will soon have access to. Something not many others care about.
