Are roadmaps a joke now?

I see memecoins launching with the most nonsensical roadmaps (if any at all) like “$1M mktcap, Coingecko listing, then $1B mktcap!” etc., and it seems to me we have reached a point of self-parody in web3. Does this imply that having a serious roadmap was never anything other than marketing fluff in the first place? Are there still projects that actually have a long-term plan? Or was the whole “economic revolution” thing a meme all along?
