Expert beginner problem. If you can count a grain of sand, and measure the distance of one centimeter, then surely you can measure the exact length of a coastline and count the exact number grains of sand! (The length and number of grains goes to infinity as you get more detailed)
It is less magic, just insanely complicated. We therefore very well might not build it one day. Your claim we would solve it one day is not obvious and needs solid evidence. Some cryptographic problems require millions of years of compute to solve, why cant it be the case that AGI requires petayears of compute? A billion fold increase in compute still won't do it, hence, maybe not ever. 4 billion years and a trillion fold increase in compute might not be enough. (Assuming we have that long. Dawkins was most concerned about humanity surviving the next 500 years.)
