meme coin is a niche on its own and it's quite resilient one, honestly trend of meme coin already here way before elon musk shill or even before 2017 as I remember.

the thing with meme coin is, it serves the purpose of being a tool for speculation, unlike other that just temporary trend because they abide to the narrative, meme coin is filled with people full of hope trying to find the next hidden gem.
since every cycle there are plenty of meme coin that made it to market cap of half billion and beyond, people keep getting their hope refueled, sorta giving false hope to keep the trend alive .

so I expect meme coin to still live on even a decade later. but if there are too many scammers, it will eventually die.
