I'm afraid I stopped following the progress of Parrot around the time of my post above, so I have no idea what has happened in the interim and cannot comment on what if anything has changed or improved.
As for what voids existed at that point in time, I would be hard pushed now to remember exactly what my concerns were. I do have a few references and emails from off-forum discussions I had at the time, but trying to rekindle my understanding of the issues now would be dificult. More to the point, most of the issues involved are a matter of history in the parrot forum archives and available to anyone with an interest.
There are also much better qualified people than I to analyse and summerise the debates that took place back then that convinced me that things were not headed in the right direction. And people who have continued to follow the project that will be better placed to discuse what if any course corrections have taken place.
Basically, "No comment".
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
