But they seem to have created a very ambitious interesting uniquotous & pervasive computing attempt. And consumer OS have basically barely bugged in a decade everywhere else.
Have they?
So far, it only runs on Huawei devices. This may be big in China, but I doubt it will sit well in other markets like the EU.
In fact, I would say that it only needs Meta to not release their applications (Facebook, Instagram, WhatsApp) on the next generation, to crush Huawei's ambitions in foreign markets almost completely.
I agree it's too early to have strong conclusions. But there's a huge range of sectors represented at a recent-ish OpenHarmony conference. Industrial, energy, vehicle uses listed. https://mp.weixin.qq.com/s/eGxegRJCKhuYz8IvsxhE5g
The use of a variety of different kernels & microkernels, bound by a common DBusSoft distributed layer, is what seems compelling to me. It means one can have very very small microcontrollers readily participating in Harmony, and ideally it means interesting Plan 9 like capabilities across bigger computing (phones/desktop/tvs/&c), where inter-system control just works. It could all go nowhere or fizzle... but I see very narrow specific heavily industrialized works like Matter, which is trying desperately just to make multiple controllers capable of running one device (an incredibly low bar for ubicomp), and I am glad & excited someone else is working to connect computing systems like Harmony is.
The technicals have some compelling ideas.
