I think they are might be a new trend for now with a lots of pumps, communities, etc. but in real world and for some serious investors they don't find it a good investment of course if you are an investors you won't buy an asset that is useless and doesn't have any use at all or a live project, right? however this trend could be a good source of profit too.
they came indeed just for the hype. some of the meme projects are serious but most of them are things that will quickly disappear. that's why serious investors won't pay attention to the meme coin that's trending right now. they are too bad in the long run and certainly too risky to put our money in there.
