Ubuntu tried this - how'd that go?
Second issue is: how do I use it? How can I install it on MY devices?
I'm all for privacy and I want to is it, just seems like a dream and it will never come to fruition
It solves a _development_ problem, in that it reduces the amount of work needed to allow an application to reach a larger number of devices. Basically the same reason for things like React Native and PWAs.

So because someone else failed at solving a particular problem in a particular way previously, we should simply give up on it?
Sounds like a repeat of the Java strategy: you can run garbage nobody wants anywhere nobody wants to run it.

Microsoft also attempted it, and also failed quite miserably.

Not necessarily, but at the very least you could avoid lying by omission (mentioning Google and Apple which don't exactly attempt convergence and pointedly ignoring every pre-existing attempt at the concept) and maybe consider humility and avoid overblown claims given you're not the first to attempt it, nobody's succeeded, there's no evidence available that you are succeeding, and you've really not shown anything which would made anyone think "this is going to succeed where everybody else failed".
