Certainly there will be astonishing advances in flashlight technology and I look forward to it. My point is that it can be nothing like the exponential growth in performance that computers have been enjoying for the last 50 years. Moore's law states that the speed and memory capacity of computers doubles approximately every 18 months, while the size and cost go down, and this is still holding true. My cell phone has millions of times the computation power of ENIAC, which filled a room. Comparing flashlight progress to this is ridiculous.
