This manifesto is just the expression of one man's fringe political views. There is a lot of rubbish in it. For example, he spends pages insinuating that leftism is rooted in masochistic, self-hating, chauvinistic tendencies. His argumentation, in the rare cases that there is any, is rather ridiculous. See, for example:
> Leftists protest by lying down in front of vehicles, they intentionally provoke police or racists to abuse them, etc. These tactics may often be effective, but many leftists use them not as a means to an end but because they PREFER masochistic tactics. Self-hatred is a leftist trait.
Of course, this manner of peaceful protest is neither masochistic nor unique to the left, so I'm not sure how he thought that this made any sense. He even acknowledges that it is often effective, and yet he still claims that it is motivated by self-hatred!
If you can highlight anything of value in his manifesto, I'd very much appreciate it.
What would a browser even need a backend for? The only valid use that I can think of is Google's Safe Browsing list, but if ad blocking can be implemented totally on-device, surely that can, too?
I think Rust has another good alternative to this, although it might be cheating a little: you can just write (lo..hi).rev(). That way, the common case of going forwards is nice, and the case of going backward isn't much worse.
Why are you crediting C++ for an idea that is probably much older than it?
