> I am not able to think beyond the end of my nose, therefore we have to stop there" is a silly response.

This is exactly what I mean by needlessly provocative. You're almost directly saying that people who happen to care more about one specific case than you do are stupid or naive rather than having a different technical opinion than you. If you genuinely think that people who disagree with you are stupid or naive, then I don't understand why you'd bother trying to engage with them. If you think they aren't, but their ideas are, I don't think you're going to be effective at trying to educate them by talking down to them like this.

> Nobody has been able to find a design that actually works yet. Which is the same problem we had with generics. Everyone and their brother had half-assed proposals, but all of them fell down to actual use. So, again, who is going to be the person who is able to think about the bigger picture and get it right?

Whether a design "actually works" is dependent on what the actual thing it's trying to solve is, since a design that works for one problem might not solve another. This is still circular; you're defining the problem to be larger than what the proposals were trying to solve, so of course they didn't solve what you're looking for. You're obviously happier with nothing changing if it doesn't solve the general problem, which is a perfectly valid opinion, but you're talking in absolute terms as if anyone who disagrees with you is objectively wrong rather than having a subjectively different view on what the right tradeoff is.

> Philip Wadler may be that person. There is unlikely anyone else in the world with a more relevant background. But, if he has no interest in doing it, you can't exactly force him — can you? It is clearly not you, else you'd have done it already. It isn't me either. I am much too stupid for that kind of thing.

Once again, this is exactly the reason that I'd argue that it's reasonable to consider a solution to a specific subset of the problem than trying to solve it generally. If nobody is capable of solving a large problem, some people will want to solve a small one instead. The issue isn't that I can't personally see beyond the end of my nose, but that unless someone comes up with the solution, it's impossible to tell the difference between whether it's a few hundred yards outside my field of view or light-years away in another galaxy we'll never reach. I'd argue that there should be some threshold where after enough time, it's worth it to stop holding out for a perfect solution and accept one that only solves an immediate obvious problem, and further that we've reached that threshold. You can disagree with that, but condescending to people who don't have the same view as you isn't going to convince anyone, so I don't understand what the point of it is other than if you're just trying to feel smugly superior.
