I thought that the good ReactOS guys were "slow" and (sometimes) a tad bit fixated on the minutiae (said in a friendly way , I know that their resources are scarce), but compared to this Open VMS people here, they definitely seem kids.
Of course I am perfectly ignorant of the difficulties involved , and definitely a "hairy reasoner" (and a grumpy one, while at it), but more than two years and the thingy doesn't even boot to print on the screen "Hello, world"
Cannot say why exactly, but the apparent pride with which they enthusiastically announce their first two "proof points" somehow makes me cringe.
Don't get me wrong, I hope that the remaining difficulties will soon be overcome and that the road map will be respected, but even if everything goes according to plans, we have a full year before the start of the (maybe) availability of the new OS.

P.S. I am not sure which is the latest-latest roadmap, but I believe it is this one, instead:
