• Most people choose a language based on quality rather than what everyone else is using
• Good languages are necessarily well known (if you build it, they will come?)
• Large corporations, which make up a large segment of the market and can basically anoint programming languages to dominance, have the ability or inclination to choose a good programming language (rather than, e.g., a language which has a strong promotional machine behind it or a language whose backer offers lots of enterprise support)
• Attractiveness to amateurs is equal to all other factors in determining a programming language's quality (regardless of what you think of the language, this is a large part of PHP's popularity)
The thesis here is simply false for any reasonable definition of "good." The only way you can make it true is to "#define good popular", in which case it's tautological.
For example, the reason there is still so much COBOL in production is not that the language is awesome and people choose it of their own free will — in fact, the opposite is generally considered to be the case even by COBOL experts — it's simply entrenched. These systems would not be written in COBOL if they were being developed today, but because they happen to have been written in COBOL's heyday, people still use COBOL. The market chooses COBOL for these positions because of the horrific cost of rewriting everything from the ground-up, not because of anything related to COBOL itself.
First, thank you for reading. This article was meant entirely to spur discussion so I thank you for taking the time to discuss.
Second, I don't think an argument that most people choose based on quality is pertinent to the theory. The theory just states that the market decides. It does not infer than any metric the market uses is inherently better or worse than others.
Third, your COBOL example is explicitly excluded from the theory as not being in a free-market. Thus it is fading away slowly. If it were truly up to the market (no external regulation from business interests) it would be dead.*
* In this case the market is defined as the direct consumers of the programming language. The programmers themselves. As opposed to indirect consumers (organizations).
It states that the market decides what? The article repeatedly suggests that what the market decides is which language is "good" or "better," which can only be true if people choose based on quality.
If the market choice is only loosely correlated with quality, then looking at the market tells us nothing about which languages are good (since "good" is a qualitative judgment).
There are only two ways I can see for market penetration to be relevant to the discussion of which languages are better:
1. The market chooses based on quality
2. "Good" is synonymous with "popular"
Otherwise you're measuring one thing and then announcing another. Market position is just popularity, and is only a reliable indicator of the things that determine popularity. If people don't choose based on the quality of a language, then looking at popularity to figure out which languages are good is like looking at the eating habits of the average American and concluding that Big Macs are the most nutritionally balanced food around because they're in the dominant market position.
Step one to making this kind of statement: give some evidence that the language ecosystem actually works as a free market.
First of all changing languages is almost always a large investment. That removes the "free" from your free market analogy so many of the assumptions you are making are completely unfounded.
Also, "free" as in choice, not "free" as in cost.
I understood what you meant by "free" but you seem to be discounting the high cost of making that choice.
You can examine the language ecosystem as a market but if you do you see immediately that it is inherently a lock in market.
Once you choose a language it's very high cost to change languages.
It's also high cost to choose a language that's not already popular, recruiting is more difficult and you will not have as much 3rd party library support.
So you have both "lock in" and large advantages for existing large players. Sure, it's technically still a "free market" because it's not regulated by the state but this kind of market doesn't have the behavior you are assuming.
What evidence do you have that these kinds of markets optimize for "better" languages?
What you might find is the market aggregate is a lagging indicator or that any summary is void of true detail.
Besides the language measurement quanta here is so far apart, no?
Say it is very popular now but it is difficult to use and no one enjoys using it. If the theory holds true, a new language will come around gain popularity with hardware firmware developers and Gabview will fade off into the distance.
For very small values of "useful" and "good"...
I have since conceded that point and removed the word "good" (which is subjective) from the post.
Also, the only evidence I have is observation. Which is why I posted the idea. To get good constructive input from people like you!
You make some good points. It is an expensive proposition to switch languages, which is why I excluded that explicitly in the post.
It is also expensive to train people. So that alone may disprove the theory. I'm not sure yet.
On a side note, as far as I know, being based on observation only does not preclude the use of the word theory. It is technically correct (at least according to the dictionary definition of theory). Although, I agree hypothesis may be better.
It's also the go to "moving the goalpost" logical fallacy used by free market ideological cranks who you don't want to be compared to.
It is not implying in any way that there is a 1:1 between popularity and quality (or any defined relationship for that matter). I think that would be ridiculous.
It is not meant as any means to grade or rank one language against the other. Only to say that a language has some value.
Rereading your comments I do not necessarily agree that the assumption is that market chooses based on quality. The market chooses based on perceived value which definitely takes into account quality but is not based entirely on it.
The implication being is that if there is truly no value or the value is so low that consumers are no longer willing to consume the product. Then the product will disappear or get replaced by a better and cheaper alternative.
In a way, it is simply saying, if someone uses a language then it has value -- at the very least -- to that person.
I guess the underlying message is: do not assume that because something doesn't have value to you that it is not valuable. If it didn't have any value it would (IFF the theory is correct -- I'm not saying it definitely is!) cease to be used.
I am anxiously awaiting your reply. If you have a good one, I might have to concede that the theory is disprove and/or incomplete.
This restated thesis could be 100% true and it still wouldn't mean that the dominant programming language isn't the worst one ever invented.
And a language with nonzero value could still be effectively worthless — if Language A is worth 1 Foo, Language B is worth 10000 Foo and Language C is worth 15000 Foo, then choosing Language A means you lose more (relative to the others) than you gain.
No one would have argued with that.
I don't think your alternative isn't quite right either.
Perhaps, I should have just titled it something like: "Ask HN: Review my theory, The Free-Market Theory of Programming Languages"
In my experience it has little to do with language quality and mostly to do with reputation and momentum. Whatever that company/team used before they will likely use again.
I'll talk about things in the web space since that's what I know best, things will be different in each market.
If it's a blue sky exercise or they decided they need something new then it's mostly based on reputation, the less popular the language chosen the more blame taken by the chooser in the case of failure. In other words, no one ever got in trouble for choosing Java, PHP or C#.
Trying to define value in a way that covers even only the big players is tough.
Java and C# are chosen because they are big (library support, support materials) and have been around for a while. They are considered trustworthy.
PHP is chosen because there are tons of cheap semi-competent programmers who know PHP. It was marketed and packaged for beginners at the perfect time and that worked fantastically.
Ruby/Rails is chosen because of marketing (the engineers might be fans, but the business guys say OK and the HR people can find programmers because of the marketing). A lot of ex-php-ers who discovered how bad PHP is as a language when they learned Ruby as their second modern language.
This is just in a small piece of the language ecosystem that I know about. Other areas of programming (other markets i suppose) are completely different but I suppose that momentum, marketing and trained workforce are factors in all of them.
I think this is too messy a problem to ever arrive at a good definition.
