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.
Yes, many of us are in the field of coming up with "the programming model" to handle this as well as general live programming problems. I'm personally focusing on optimistic techniques to deal with concurrency as well as incremental code changes.
