Whoever speculated 1000+ dapps would be on EOS was selling pipe dreams. Why anyone believed it was their own shortcomming in foresight.
Ethereum sharding is like the LN, I think it's not scaling. They can call that scaling, but if you can scale on-chain I prefer that.
The EOS model for scaling is the same type of model that forward thinking Dash is aiming toward. Dash did not begin with a model that fascilitated scaling, but they're moving in that direction. It's the future.
Is scaling properly enough to de-throne Ethereum? Maybe, maybe not.
Does EOS need to beat Ethereum? No. It just needs its own economy for what it can successfully provide. Expecting tons of things from EOS 1 month after it going live is asking a bit much.
I am probably giving EOS until late 2019, before I would be willing to decide it's not viable or not good.
Is it worth buying now? Maybe not. My EOS projection is still only $100 if it does really great, so that's only a 10x. But anyway, app developers don't even yet understand how EOS could be utilized successfully to do things never done before. That's what is required with EOS, that people realize, "Oh, it can accomplish what Ethereum never will."
Ethereum sharding may give it more functionality in the long-run, and it keeps them from being abysmal, but tier 2 solutions are basically long-term bad.
As for 1 mil transactions per second, it can certainly do it on paper, but its not needed at the moment. It's easy to scale if the baseline premise of the network is that you have less than 100 block producers all using backbone servers in major cities worldwide. Scaling is not really an issue. Right now, I think they're focused on getting the different locations live and operational so that consistency for the network is established. Once the network is established, if people actually legitimately used it to do things and it actually arrived at the point it needed to scale, then it would be able to do so by design. My guess is at start-up they're relying on network nodes that may not be ideal in all situations.
