> Libraries aren't the issue

You say libraries aren't the issue, but the discussion is about a blog pst that said: "And why Python, then? Well, said Sussman, it probably just had a library already implemented for the robotics interface, that was all."

I'm sure your experience is grounded in a general reality. But the post you disagreed with was about a specific case: i.e. the one described in the blog post.

From the point of view of a person at an instant in time, libraries are a concern. But when we're talking about Scheme being displaced by Python at MIT, where Scheme was developed 30 years ago, we really ought to ask what's been happening to Scheme during that 30 years.

The problem, at MIT and elsewhere, is that hackers don't like hacking Scheme enough. Python has more libraries than Scheme now, but that's not the main thing that made more people use it. People use it because they prefer the language. This is something that Sussman and others at MIT should be trying to understand, but it doesn't strike me that they are trying to understand it. They're just saying "Python has a better robotics library -- oh well!" as if this were something completely random that they have no control over. That doesn't seem like the sort of attitude that produced Scheme in the first place.

My point of contention with the comment I replied to is the idea that fixing the problem is a question of writing more libraries for Scheme. Writing or interfacing to libraries for numerics, 3D graphics, etc. is a trivial task compared to making a language hackers love.

Now, maybe hackers' distaste for Scheme is Scheme's fault, or maybe it's hackers'; but in any case, the issue is with the core language, not the libraries. And based on my personal experience with Scheme I would say that enough of the fault lies on Scheme's side that it's worth fixing.

The prospect of Scheme as a potential mainstream programming language went down with the rest of the Lisp ship in the late-1980s AI winter - the same one that sank Symbolics and anyone who was remotely Lisp-guilty by association.

It is no accident that it survived almost exclusively in non-saltmine sanctuaries like MIT, where industry herdthink held less sway. In the linked article, Sussman directly admits that he is unable or unwilling to fight back against the intellectual decay that has consumed non-academic programming.

He has decided to "go with the flow" - namely, the flow of industrial sewage into students' heads.
