I don't think that comparison is fair at all. You're comparing concerns of a technology and how it scales, to how no one talks about physical keyboards and smart phones? That's not even remotely the same and is pretty dishonest to make that comparison.

The problems of solar as a scalable renewable are very fair to talk about, considering that Africa and India NEED energy to grow their societies. The only solutions that scale are oil or nuclear. The idea you can just hand wave any concerns about renewables doesn't seem very rationale if you genuinely care about the problem.
