Bitcoin doesn't scale. Saying that 3rd party companies and offchain transactions will solve this goes against the very idea of bitcoin.
Also the deva saying "ohh, don't worry, we will look into it when it becomes a real problem" is a very bad sign IMHO.
Not true. The devs have been saying for quite a while "we're looking into it, and we'll be ready with a solution by the time it becomes a problem", which is quite different.
What you're suggesting is turning the steering wheel now because there's a bend in the road three miles ahead.
He's right, the steering wheel might need to be turned sooner than you think. Remember what Erik Voorhees did to the system with SatoshiDice? When confronted about bombing the blockchain with micro transactions he didn't care because he was "testing the system". Greed will force things on Bitcoin before it's ready. The only thing that can really destroy Bitcoin are the users or lack of users (see my previous post above).
