Rushing to optimize before the bottlenecks are known may be the only error to have ruined more designs than feature creep. From tortured code to incomprehensible data layouts, the results of obsessing about speed or memory or disk usage at the expense of transparency and simplicity are everywhere. They spawn innumerable bugs and cost millions of man-hours - often, just to get marginal gains in the use of some resource much less expensive than debugging time

I believe, but cannot prove, that global “AIDS” is a whole cluster of unrelated diseases all of which have been swept under a single rug for essentially political reasons, and that the identification of HIV as the sole pathogen is likely to go down as one of the most colossal blunders in the history of medicine.

Thompson and Ritchie were among the first to realize that hardware and compiler technology had become good enough that an entire operating system could be written in C, and by 1978 the whole environment had been successfully ported to several machines of different types.
