Of course I would, Ethereum now is bigger than just Vitalik Buterin alone, I know he's influence in the ethereum community cannot be undermined, But Bitcoin still does exist and is doing pretty great with the absence of Satoshi, even though is presence would have obviously made Bitcoin better. Vitalik absence will be duly felt but, that doesn't mean the project can't continue in his absence.
You're pretty right. Not only bitcoin, but doge also like that. From there we should be able to think, not always when the founder leaves, a platform will fall. Support from the community really can make dogecoin continue to live until today, especially with ethereum which has a community greater than dogecoin.
