Rob Pike's talk about the motivation for Go is rather fun, but doesn't really break new ground. Most of what he says have been said here many times, from the critic of the verbosity of C++ and Java to the skepticism about dynamic typing. Some small details are perhaps worth arguing with, but in general Pike is one of the good guys -- it's all motherhood and apple pie.

So why mention this at all (especially since it is not even breaking news)? Well, what caught my attention was the brief reconstruction of history the Pike presents. While he is perfectly honest about not being interested in history, and merely giving his personal impressions, the description is typical. What bugs me, particularly given the context of this talk, is that the history it totally sanitized. It's the "history of ideas" in the bad sense of the term -- nothing about interests (commercial and otherwise), incentives, marketing, social power, path dependence, any thing. Since we had a few discussions recently about historiography of the field, I thought I'd bring this up (the point is not to target Pike's talk in particular).

Now, when you think about Java, for example, it is very clear that the language didn't simply take over because of the reasons Pike marshals. Adoption is itself a process, and one that is worth thinking about. More to the point, I think, is that Java was (a) energetically marketed; and (b) was essentially a commercial venture, aimed at furthering the interests of a company (that is no longer with us...) Somehow I think all this is directly relevant to Go. But of course, it is hard to see Go gaining the success of Java.

All this is to say that history is not just "we had a language that did x well, but not y, so we came up with a new language, that did y but z only marginally, so now we are building Go (which compiles real fast, you know) etc. etc."

Or put differently, those who do not know history are doomed to repeat it (or some variation of this cliche that is more authentic). Or does this not hold when it comes to PLs?
