Look how far we've come from the Apollo guidance computer, which landed 3 men on the moon, and had a fraction of the power of almost all of today's cell phones.
We can see this as a testament to the skill of the mathematicians and software engineers who worked on the Apollo team. These guys didn't have the benefit of pre-built algorithm libraries or computers with processing power to spare; they were like early explorers crossing the Atlantic in wooden sailing ships without a map or compass.
