... and it's pretty pointless. No bugs? You are certainly joking, or at the very least, clueless.
There are *always* bugs and always will be. So what? Many bugs just aren't worth fixing, and are even debatable as a bug. Bugs come in all forms:
A) The software doesn't do what it is specifically designed to do. (obvious, must fix)
B) The software does exactly what it's supposed to do in an insecure way that can be exploited in some fashion. (probably should fix, unless the "insecure" way is part of the assumed envelope of use. For example, the common practice of using an SSL reverse proxy got Google in trouble with the NSA yet using a reverse proxy isn't itself generally considered a "bug".
C) The software does what it's designed to do, but not in a way that the user expects. (Is this a bug? Or PEBCAK?)
D) The software does what it's supposed to but not when an unexpected environment is encountered. (Example: this product is incompatible with A/V $FOO)
E) The software interacts with other software in an unexpected way.
F) The software lacks a feature that some customers would find useful.
G) The software implements a feature in an unattractive or cumbersome way. ... and so on.
A PENCIL has bugs! Yes, a pencil. The lead breaks easily. The eraser doesn't remove *all* the marking when you use it. It requires a sharpener. You can't sign a contract with a pencil. They are horrible for lefties who end up with a dark stripe on the side of the their hand. The paint can sometimes discolor your finger. And on and on and on...
These are all "bugs" yet the design of a pencil hasn't been updated to fix them. There are few things as simple as a !@#$% pencil yet these obvious bugs have *never* been fixed. Oh sure, some have. There have been erasable pens. There are mechanical pencils. Pens can perform some of the duties of a pencil.
So if a bug-free pencil hasn't yet been made, how in the name of anything holy do you expect something millions of times more complex to be "bug free"?
