The Alexa rank is not that important (that only measures the visits to the seemit website which is only one application built on top of the Steem blockchain).

For that reason the view count is not that relevant, a post can be viewed on different websites (like busy.org for example).

The Steemit website could become irrelevant but others could easily surpass it (Dtube or Steemmonsters come to mind or the multitud of wordpress blogs that use steempress to connect to the blockchain).

Value wise steem has outperformed bitcoin since March of 2017 (just look at the price in Satoshis).

The Steem blockchain is one of the most active blockchains in the world (check out https://blocktivity.info/). If Steem is dying imagine what will become of all the other ones that pretty much have zero activity.
