Ray Kurzweil is speaking at my university tonight. What questions should I ask him?

I'd like to ask RK why he believes in homeopathy:

And what he plans to do when he realizes in another few years that nothing will happen within his remaining actuarial time budget to make him "immortal," despite his delusions about building "bridges to immortality." I've read conflicting claims about RK's cryonics arrangements, for example. Instead of squandering his remaining cognitive reserve and reputation on his singularity delusions, he might want to reconsider investing them into making cryonics a more feasible means of survival for himself.

Does he still predict that mind uploading will be possible by 2040?

If not, how does he explain the change in expected timeline, and why should people expect the same factors won't apply to his new timeline?

What he intends to do to secure Friendlyness.

I'd like him to account for his inconsistency on exponential growth in solar, where for every other technology he displays exponential growth in performance/dollar, as he should, but with solar, he talks about exponential growth in installed base.

This question I see relevant to him:

The LAR and the light speed principle, they are not reconcilable, something has to give. What probability he assigns that the speed limit c has already gave up, last year in Gran Sasso? Especially in the light of current doubts about how good the cable connection was in the measuring equipment.
