There are only a few hundred users left in the system - kiss the upvote hand so it won't happen that way. I believe Steem will find a new way that will attract most of the old active users, inactive users, as well as the mass of new investors from around the world.

Will Justin port everything over to Tron once he has full control?

I don't think it's going to ruin Steem.

So, is that a yes but it won't ruin steem?

NO

And what do you mean about the upvote hand?

Only those who follow blindly those who can reward them have success.

Is that a knock on the system?

Only normal evolution
