I don’t think it’s very good reasons. We could definitely have binary first serialization protocols and good tooling built into the browser. But no, we encode everything as text, even binary stuff as base64, and whack that into strings

There is nothing preventing anyone to build a whole new set of infrastructure for such "binary first serialization" 20 years ago, 10 years ago or today. We don't even need to do that much. Instead of "text/html" or "application/json", let's just use some binary format in the request headers everywhere and make both the client and server support it. Why hasn't that happened?

It's for the same set of reasons, and people aren't dumb.
