Not to mention the fact that SegWit testnet forked and that there’s no way this thing will be ready in a month. (Ok, I mentioned it.)
Nonsense. You can't possibly know that. The reason for which it is called a testnet is because it supposed to be used for extensive testing (which it is). I'm actually 'glad' that the fork happened there, else something might have been missed before the release. It could be a simple bug, you never know.
This economic experiment we're running right now, where txs are at the bleeding edge of the block limit with the entire network susceptible to ddos attacks, and later, hopefully(as in: if genuine txs keep growing), users being pushed off the network because of full blocks; is very, very dangerous.
Still less dangerous than a contentious hard fork. Gavin had one job: 1) consensus threshold (90-95%); 2) Grace period (even Garzik suggested 3-6 months as a minimum). He failed miserably on both.
