To discuss needs a little bit of honesty. You get your arguments about
the fact I spoke about a vms 5.5 case. I had to say my analysis around
vms is not based on this specific case.
For this discussion I think there are a difference of point of vue. My
opinion here is althought often we can say "the tree hides the forest",
I hear your analyzis as "a forest which hide the tree".
A lot of (important) details sometimes hampers consideration on
fondamentals. The revival of VMS is far from a set of details.
And a lot of contextual causes doesn't everytime prevent success of
cleverness. The VMS x86 port is one of these stories.
I remember how "poetic" was thought here my analysis on a potential
revival of VMS - and there was a lot of contextual good reasons to think
like that -. And it seems it has been my fundamentals (poetics) which
has been right.
Your analysis are very usefull and always full of precious information.
Try also synthesis.
