And now, a brief definition of the web

What exactly is the web?

It seems like a stupid question because we all know the answer: the web is the thing Tim Berners-Lee invented in 1989. It's not the same thing as "the internet," which is what we use to access the web, apps, and streaming video. It's what we visit every day with our web browsers on our phones and laptops. Simple, right? Well, no. Traditionally, we think of the web as a combination of a set of specific technologies paired with some core philosophical principles. The problem — the reason this question even matters — is that there are a lot of potential replacements for the parts of the web that fix what's broken with technology, while undermining the principles that ought to go with it. The tech you think of as "the web" is HTML, Javascript, and CSS. (For simplicity, I'll just refer to it at the "HTML stack.") Those technologies are so open and flexible that they've taken over the world. That very flexibility also means that they've been abused, slowing down the mobile web with trackers that invade our privacy and deplete our batteries. So a lot of tech companies are flailing around looking for ways to fix this problem.
