i believe it's not dead yet. the doge community is active and doing good since a few years ago. then elon musk came and made a high impact for doge price. i think the doge community can handle it even if elon musk is gone.
You can say but Elon has no more influence on Dogecoin because now Dogecoin is on its own way. Elon pumped it a lot and now Elon has no much value against Dogecoin.
And yes the Dogecoin community is active and the team is working more to improve the core of Dogecoin.
