I really don't think making protocols less understandable by humans will solve anything.

This has always been and always will be a hard problem. Consider this quote which I found in The Shellcoder's Handbook:

"Wherever terms have a shifting meaning, independent sets of considerations are liable to become complicated together, and reasonings and results are frequently falsified." -- Ada Lovelace

We've known about this since literally the beginning; we'll be cursing ourselves over it until the very end. Vulnerabilities are going nowhere.

It's not about making protocols less understandable by humain, it's about recognising that we are programming computers, not humans and that it's time we accept that there should certainly be a way for the humans to interact with the program at some point we should not force the same kind of interactions on the programs themselves. It's much harder to make text and text based commands' parsing and handling secure than it is to use binary protocols in the first place.

I just disagree. You seem to be saying we should use binary protocols and load them directly into memory Cap'n Proto style. But what if I'm little endian and you're big endian? Parsing happens. Text-based protocols fit well into human's heads, and its the humans that have to do the debugging. I think it would only make the process of finding bugs slower and more complex, and give advantage to the attackers.
