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.
