Every coin meme has no future direction because it is created by individuals and teams just to pursue trends and profits for them after which it will become a joke coin again. only a few meme tokens survive if the developer is serious about management and works hard so that the meme token has a high value. For investment, it is still very vulnerable to losses, so you should be more careful with meme coins.
I second you all your points are very valid Memecoins have no future except few because they are made just to catch the market trend as memcoins are trending so developers made such coins just to fill that market gap. Not recommended for long term investment yes you can invest in Memecoins with low capital so you will bear that loss without heavy heart.
Their volatility kills them usually. And, memes will always be there, just on different chains and networks, in my opinion
