I mean the quotes in this article aren't even disagreeing except on vague value judgements with no practical consequences.

Yes you can make better and more perfect solutions with a deep understanding of every consequence of every design decision. Also you can make some real world situation thousands of times better without a deep understanding of things. These two statements don't disagree at all.

The MIPS image rendering example is perfect here. Notice he didn't say "there was some obscure attempt to load images on MIPS and nobody used it because it was so slow so they used the readily available fast one instead". There was some apparently widely used routine to load images that was popular enough it got the attention of one of the few people who deeply understands how the system worked, and they fixed it up.

PHP is an awful trash language and like half the internet was built on it and lots of people had a lot of fun and got a lot more work done because people wrote a lot of websites in PHP. Sure, PHP is still trash, but it's better to have trash than wait around for someone to 'do it right', and maybe nobody ever gets around to it.
