I agree with @taskmaster4450, those two shouldn't be ever compared.
Doomed? No.
Steem is long time gone. It's no longer decentralized platform. It's an empty shell drained by Sun with only one objective - to pump his copy&pasted projected called TRON.
Oh and by the way, future of TRON is same as Steem because in both cases there's a huge pile of assets that are "not supposed" to take part in governance, etc.

Sounds familiar?
Meanwhile, @steemit account on Steem is powering down nearly 30M tokens, over 18M were already transferred to Binance.
