Based on what do you say this? I have my browser set to non-geographically specific, and when I ask programming questions to it, there are many, many answers in chinese and japanese. If the programming languages statements themselves were in those languages, a chinese or japanese speaker (in my field) would not need english at all.
From my experience the amount and the quality of resources available in English is simply not comparable with any other language. Surely it is possible without but much harder. I am Italian, during my studies I had the chance to read technical books both translated and in original language. The translation is usually very poor. On a daily basis work scenario, no Italian online resource would come close to stackoverflow to help diagnose issues quickly. Moreover, it takes time for official documentations to be translated in other languages. Even years in some times. It really depends on your sector. If you work in a niche area where you don’t necessarily need to be up to date with the industry you could survive without English.
I am italian as well, and I was specifically talking about chinese and japanese.
