My point is that we'll continually find better solutions to existing problems (concurrency, or anything else for that matter). There will be a time in the future when we've come up with a solution that's "good enough", and it'll become the de-facto standard for a while (kind of like what Java is today). I don't know what that solution will be, and I don't speculate about it: I'm more interested in the solutions we have today.

Yes, the raw solutions _are_ very painful, which is why they haven't seen widespread adoption. And yes, we are continually trying to enable more programmers.
