The author made lots of unsubstantiated and even nonsensical promises such as green threads with no runtime or the supposed C++ to V translator which would be a HUGE breakthrough in compiler technology because such a tool would be (as was exactly shown in an example) able to understand programmer's intent.
He just stringed together attractive looking words and phrases without really understanding what they mean.
And of course, none of the promises actually materialized, so either Medvednikov is grossly incompetent or a pathological liar. You decide which is the case.
I made a program called rkvm which works on a level below display servers (works with uinput directly) and thus doesn't suffer from these problems. Currently, it only supports Linux and Windows, where only client support is implemented on Windows, but it works well for my use case.
Glad to hear such kind words. :) I haven't personally tested it on Wayland because I'm an Xorg user, but there should be no reason why it wouldn't work. If you find any problem, feel free to open an issue and I will look into it.
Ironic that the author calls people fools and then proceeds to advertise Gemini as if it has any chance of succeeding outside the small group of people interested who will probably forget about the project in a few years anyway.
