Persistently near-exponential growth over multiple decades isn’t impressive to you? If this carries on, peak PV output alone will exceed 100% of current total power demand by 2030.

(Naturally this means I think the growth seen since 1992 won’t last until 2030, but the point remains)

Assuming that exponential growth will be steady is a very risky assumption. Where's my single-core 100 GHz CPU? Moore's law says we should have that by now.
