Wisdom consists of knowing when to avoid perfection. A computer makes as many mistakes in two seconds as twenty men working twenty years make. There exist unthinkable thoughts. Microminiaturization just makes the problem harder to get at. Flaws found in the program will usually turn out to be flaws in the system, but never vice versa.
Fallible men design fallible computers.
One accurate measurement is worth a thousand expert opinions. By definition, when you are investigating the unknown, you do not know what you will find or even when you have found it. If a system is of sifficient complexity, it will be built before it is designed, implemented before it is tested, and outdated before it is debugged. When a distinguished, but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
