As a biologist, I've got to point out that our entire existence is based on evolution gluing together whatever was around to fill a niche, without thinking about proper engineering. Which is why, to give just one example, the nerves in our eyes run in front of the light sensitive cells, necessitating a blind spot where the nerve leaves the eye.

More seriously, I think we as humans benefit much more from getting technological developments quickly, than we would by waiting years or decades for them to be soundly engineered first. I doubt we can even foresee all the possible problems until we start using things at a large scale.

Good point. A valid counterexample would be the well though out text book examples of minix (and gnu hurd) vs Linux.

Sometimes paralysis by analysis is a bigger problem than bugs and bad architecture. And often the alternative to "usable" isn't "perfect" but "never shipped".
