Were you on Youtube in 2005? It would have been a bit different wouldn't it?

What we were left with was just another platform that's there as a secondary back-up, like LBRY.

I don't think people have yet understood the importance of this. Those who do understand are going to be able to build and leverage a new economy while the others are likely continually going to be under pressure on their 'home' platforms.

Maybe in a few years (if it's not replaced by something better that actually invested in developing itself when its currency had value instead of investing millions in dLive), Steemit will be a viable alternative for content creators.

The only people who invested millions into dlive were the investors that paid for it before they were on Steem. They made something like 70,000 from Steem if I remember plus a few more thousand fot their circlejerk team members.

Until then, the burden of growing the platform is put on the content creators, which isn't really an optimal situation,

No, content creators are only one part of the equation here.

since a content creator is a bit busy actually making stuff, not marketing one of the dozen platforms they put their content on, hoping that it'll reach an audience it will resonate with.

Even in that video he was marketing Twitch.

Luckily, Steem is an opt-in platform that no one needs to be part of if they choose =)
