I personally think dogecoin is dumb, but I also don't think originalism is very useful to judge most creations. Plenty of creations take on a life that is nothing like the originator intended.
Maybe, but it’s not like Bitcoin had a mission and it’s now completely different, it still pursues a more decentralized world view. In similar light, it’s not like Dogecoin is now any less of a joke than it was when it was created, it’s just speculated upon more.
