Yes, think of all of this as an evolution, either an animal or ant being grown, or more the very first few web servers/browsers. So yes it will be this fragile as we move on, getting stronger all the time.
There are two paths to this.
- Until all the features are in place, like payment by resources for resources (or simplistically safecoin) then it cannot be considered "strong".
- Even with all features in place there will be both bugs and much much better fundamental "rules" within the network. So even then it may be somewhat fragile, thats a tougher one to reason.
So we are heading for 1. and for 2. we are heading for minimal, perhaps slower that we anticipate.
On this issue, @Viv and I have been talking and I will do a blog post about this. We are not rebuilding the Internet as we know it. We have used the analogy of us building a quantum computer and everyone wants to run tetris/doom and word/excel on it, but it's much much more than that and a secure autonomous network can allow so so much more than secure way of playing games or web browsing.
In saying that secure messaging and data storage is bigger than we all realise at times, but it's more than that, and more than "secure super mario" even if cannot run super mario as we wish it to. Sort of like Tesla [edit cheers @BIGbtc ] cars produce nothing to feed our plants like horses did (I realise that is a sh*t analogy )
Anyway I ramble, hope this helps.
