I'd love to try my hand at reading it. Chinese is my stronger language, but I can read a lot of Japanese for meaning.
Agreeing with your point that everyone, especially a native speaker of English, is well advised to learn the language of customers, I still agree with Jeff's main point that if we want an interlanguage (a "lingua franca") for programming, that language will have to be English for the foreseeable future. Not because Japanese and Chinese and Korean people are unimportant, but for the same reason that Japanese and Chinese and Korean people very often use English for conversations among themselves that include no native speakers of English--an interlanguage gains usefulness from network effects, and English dominates all other conceivable choices of an interlanguage in its network advantages.

Let me hum a few bars: if your customers don't speak English, and your colleagues don't speak English, and your business partners don't speak English, then your refusal to use languages other than English cannot be justified by it being efficient. It is hubris to think otherwise -- an arrogant sort of laziness of thought which is entirely different from the productive laziness that programmers generally cultivate.
A programmer who cannot talk to his colleagues and customers, and blames his inadequacy on them, is a failure at his profession : writing code which solves problems for people. If you only get as far as "writing code" without understanding the people and their problems, congratulations, you fail.
On the plus side, the prevalence of attitudes like this means you can do pretty well for yourself if you're bilingual. I got stopped on the train today by the guy who got me my current job (random coincidence -- we live in adjacent small towns). He started the conversation like he always does "Hey, Patrick, how's work? Say, do you know any bilingual engineers looking for employment?"
This week apparently its an aerospace project that needs them. Its always something -- there's hundreds of billions in trade happening between the US and Japan every year, huge portions of it are high-tech, and engineers here are only marginally better at speaking English than engineers in America are at Japanese. (In my experience, though, they're not aggressively proud of being ignorant.)
