What we should do is not "make good new things" but "maintain things that work and improve upon it".
We have too many people that WANT to make new things. Ideally good, but when so many people value NEW things we obfuscate what good means.
Maintaining thing that works includes everything: it makes you learn something,(how can you maintain something you don't understand?) often structured and you stand on a giants shoulder. Since it have been maintained so far, most likely it's also valuable. But also, most likely it can be improved upon.
I think PGs essay here actually go against his previous post of "Great Work". In this essay he mention art needs to be new/unique but usually art (and fashion) is cyclic; they reuse and rehash old ideas all the time.

The idea of dividing people into two categories: 1) those who "take care of people and the world", and those who 2) "make good new things", is harmful.
This is what makes silicon valley is so amazing. It's filled with those who want to make good new things, who aren't afraid of looking awkward. This type of culture is actually quite weird. In most other places, you'd be dissuaded by conventional wisdom, or "who-do-you-think-you-are-isms".
It's crazy you think this is even remotely unique to SV. Broad swaths of the country (referred to as "flyover" by coastal people) are fully employed in the production of new things that are essential to the survival of the human race.
