THey will definitely have a place in the ecosystem for a long time to come but hopefully it will be a healthier position for promotion of content that should be seen and rewarded.

so measuring what is good content will once again be front and center.

I think that while there will be some initial issues, this can really only be a good thing for the long-term. With various interfaces and eperiences based on SMTs, there will be space for lots of reward models on different kinds of content too so a meme won't have to compete with the release of an original album like they do on steem.
