You're right in that we kept the best examples (as coding museums will do in the future) but the best of something is a benchmark. It is striking that modern automation, even hundreds of years later, can't touch what a skilled craftsman could do in the past.

With programming, we documented a lot of it, so it's unlikely to go the way of fine weaving. People will always be able to learn to think and be great programmers.

Maybe if the wool weavers had internet, they could have blogged, made youtube videos, and cataloged their profession so it could last Millenia.
