Do not reply to the panic-stricken technologically illiterate trolls.
Can we respond to the literate ones?
Did we fail to?
I don't believe you responded to me yet
This was addressed:
How about for proof just go run a DApp? There are plenty of smart contracts out there live and functioning on the network right now.
Capser is for scaling.
Capser is for scaling.
Here:
Sorry, a bit more precise: Is casper the base for the Smart contract executor?
No... smart contracts are already a reality without Casper.
https://etherchain.org/contracts
Smart contracts in a real world setting that must scale can not exist without Casper.
The virtual machine for smart contracts runs, but any sort of real world scaling of the virtual machine requires Casper.
I have explained why Casper can't possibly work and my point is unarguable.
And here:
Its really pointless to have a general discussion without reference to specific application. One thing is for sure: the slowlness and lack of concurrency greatly limits possible applications. What worries me is that Vitalik is computer science drop out and he may have missed some of the important stuff that people suppose to study 
The whole thing about Ethereum seems to me like a strech of imagination that may lead nowhere. Blockchain is very specific thing created for very limited and specific purpose and so will be possible applications of Ethereum which I see to be mostly limited to transactional stuff. These applications will have to be quite simple, no heavy processing is going to work well in such archetecture. I really would like to see very specific ideas for Ehtereum apps and not general stuff that is theoretically possible.

And it won't even scale to where Bitcoin is now decentralized because scripts consume more validation resources than validating ECDSA signatures.

For example, I long ago shortcut directly to the generative essence of the problem space and thus am not wasting everyone's time and $millions pursuing braindead designs that can't possibly work. Instead I understand that validation must be centralized in any possible consensus system and thus I turned my attention to decentralized control over centralized validation. Those guys are instead still stuck back at figuring out what can't work.
