Some schools have a bifurcated curriculum, like Indiana University which has a program in Informatics for those planning to go into a career the requires programming and software engineering skills and a program in CS for those perhaps planning on going into grad school. There, learning Haskell might make sense in the CS program, but does it make sense for other students that want to get out and get a job?
My own daughter studied at a school where her first CS class was taught in Scheme (Racket). It, to me, looked like an excellent introduction to programming for someone majoring in CS. They used a book I approved of, How to Design Programs/2ed by Felleisen, et. al. Would Haskell have been better? Maybe, but I predict that more kids would have serious problems with a language like Haskell that is burdened with more challenging concepts and ecosystem. Perhaps Lisp/Scheme is a gentler introduction to applicative programming than Haskell. However most schools start with Python or Java.
I understand the arguments for a strongly typed functional programming language like Haskell (my own university research was in program verification many years ago).
Early on in CS programs students usually take one or two classes on data structures and algorithms. Data structures in my opinion needs to be taught in C. Haskell, Lisp/Scheme, Python, Java, and even modern C++ are so high level that teaching data structures in these languages ends up with students not learning the proper use of these languages' standard libraries.
At some point undergraduates should have an introduction to systems programming, the best text in this area is Computer Systems: A Programmer's Perspective/2ed by Randal E. Bryant and David R. O'Hallaron. This is a great book for undergraduate CS majors. This book requires C programming. So to me, it makes sense to teach data structures in C since students will need to understand it for their first exposure to systems programming.
Where should Python fit in the curriculum? It's arguably the most versatile programming language. What about Javascript? When should CS majors be exposed to it. Modern Java is a big language so one semester of use isn't going to be enough and it's too important to ignore. What about C++? It takes years of working with it to become a good but not expert programmer in C++. Should it be a part of the curriculum?
So my own recommendations for an undergrad CS program's language choices would be:
* Python -- for intro to programming, a course on algorithms, and a machine learning course
* C -- for an early class on data structures and a later class on systems programming
* Java -- software engineering, and a compiler course
* Lisp -- programming languages smorgasbord course, and an AI course
* Assembly -- hardware architecture/digital design course
* Javascript -- taught as part of a web-applications class
* Haskell or OCaml (or maybe Rust) -- intro to functional programming and program verification
What do HN readers think about this list? I'm glad I don't have to make the real decisions there are just too many languages that students need to learn in just a few years.
As far are my own background I have spent a great deal of time pursuing three different degrees from three different universities in CS. I've been the instructor for university courses for CS majors twice and taught perhaps 40 week long classes to professional programmers within a Fortune 500 company. I've also interviewed and hired many senior developers for my own company.
I am a lawyer. I didn’t learn Westlaw or Lexis in law school. I mean yes, I did use them and was trained in them. But they were just tools. But no one would say “what computer research system should we teach our students?” And good thing—the ones I used in law school are now obsolete!
Even as a lawyer I can teach myself programming languages. Man I’d be disappointed if I went into a university CS course and they’re debating something as low level as what language to teach me, rather than teaching me how to learn any language and how to design new ones.
As a practical example, in my graduate program, there were some courses where the professors handled a lot of those baseline details, and courses where the professors gave a lot of leeway to the students. My observation was that the latter courses couldn't go nearly as deep into the official topic of the course. Students would spend so much time managing their programming environments that it became a serious distraction.
Also, in reference to your question, "Isn't the language just a tool?" - no, it isn't just a tool. It's also a language. For a professional software engineer, the programming language isn't just a way of telling a computer what to do; it's also the primary, and most authoritative, medium by which you communicate complex technical information to your colleagues. It's perhaps comparable to the divide between informal language and legal language - one is useful, especially for communicating to people with limited expertise in the field, but the other is where the rubber actually meets the road.
I am a software engineer. I didn’t learn RequireJS or CommonJS in school. I mean yes, I did use them and was trained in them. But they were just tools. But no one would say ‘what JS module system should we teach our students?’ And good thing—the ones I used in school are now obsolete!
Even as a software engineer I can read court opinions. Man I’d be disappointed if I went into a law school and they’re debating something as low level as what jurisdiction’s laws and court decisions to teach me, rather than teaching me how to interpret any law or legal argument and how to design new ones.”
I hear what you’re saying, software engineer, but avoiding any particular set of case law would leave these lawyers extremely unprepared for professional practice—not just because they will likely work in one of those legal codes otherwise covered by the school, but because those codes and the arguments that shaped them constitute an immense base of empirical knowledge about legal rhetoric, logic, and concepts that simply cannot be replicated in a vacuum. Accordingly, those excellent judges and legislators who do the novel work of lawmaking and legal argument are _not_ reduced to technicians by their knowledge of case law. In fact, I’d say it’s the opposite: it is impossible to have a good grasp of the theoretical underpinnings without also having extreme facility in one legal code or another as a ‘native tongue’.
Yes. But to learn the data structures and algorithms you have to practice coding them. What language do you code them in to teach them? After awhile most code looks the same.

Yes and no. YMMV

It's really a disservice to students. Developing competence in a variety of programming paradigms is a career-expanding experience. It makes picking up a new language - and, by extension, a new technology stack - a quick and easy thing to do, because there will be very few ways of doing things that you haven't seen before. Which, in turn, makes it a lot more feasible to pivot your career or act quickly when an opportunity arrives.
A bunch of students who know only Java, on the other hand, is exactly what big corporate employers want. For employers, it maximizes the interchangeability of employees. For employees, it minimizes the interchangeability of employers.
Where would that be? Why is everyone here avoiding being specific? If you are not specific, why should we believe in what you say?
The most practical way someone could act on the opinion I expressed, if they find it useful, is not to sit and laboriously compile a list of individual institutions. It's to take that opinion under advisement in the course of the due diligence they should already be doing in their college search.
As for the last question, if I had any fiduciary responsibility, I would advise you not to believe anything posted on an Internet message board, because the commenters are largely just a bunch of anonymous yahoos who like to troll high school juniors and seniors as a sort of perverse hobby.
If you want people to name and shame, ask for a list of offending institutions, not individual examples. (Also, fact-check that list, rather than blindly accepting accusations made by internet randoms, but that should go without saying.)
If your first program is an object, the whole world becomes an object.
