I don't know whether it is possible with chip development or not. But I really hope that this project will enable numerous amount of derivative chips just as Linux kernel allows multiple distro. That means IoT/GPU/CPU/etc chips need not to start from scratch. In addition, having similar foundations might help fabs manufacture those chips swiftly.

That's the whole point of open source hardware. Unfortunately most of the licenses used are not reciprocal and this does not encourage building ecosystems.

  In the readme, they list three components that were sourced from other open-source projects: https://github.com/OpenXiangShan/XiangShan/blob/master/README.md#acknowledgement https://github.com/OpenXiangShan/XiangShan/blob/master/READM... So it seems like there already is a little bit of an ecosystem.

    I think the hardest problem is contributing changes back upstream. With hardware, people are a lot more paranoid about introducing new bugs and I feel like that sometimes makes collaboration a lot more difficult.

So at least they're aware of the problem, although that doesn't guarantee that they'll fare better in terms of attracting outside contributions.

        Oh man it’s starting, we will have to learn Chinese to get access to the whole picture of all the information out there. Some weeks ago I already heard that there are really good VUE.js sources in the Chinese web. This is quite terrifying, it seems like it is only a matter of time until state of the art scientific papers will only be available in Chinese :(

        I think you have already been underestimating the quality of resources available in French, Russian, German, and others, that do not exist in English. Just as a single example, the math section of the French Wikipedia was distinctly superior to the English one when I was in college (2012).

        If you're into OCaml, French is a very handy language to know in my experience

        I can testify to the superiority of the math sections in French Wikipedia. They were so good I lost many hours just wandering.

        France's #1 export product us culture so I am not at all surprised. They also invest lots of money in this. French cultural centeres abroad are more funded and in many ways better than any other embassy operation.

        When I was into university, lots of great 3D papers were available in German.

        So many of us speakers of other languages had to learn English. Now you’ll just have to join us in learning Chinese. It’s not that hard, just very different.
