Talk Morgan Forums Thread Like Summary - Silicone vs. ordinary brake fluid

Recently there has been a thread about brake fade, possibly due to old brake fluid. Silicone fluid was mentioned, something to avoid. But why? I have heard many reasons, but what is really true, what is myth. I am not embarking on a crusade for or against silicone, but would really like to know what are proven facts and what is beliefs just passing from person to person citing each other.
I have heard:
Silicone will make rubber parts in the system swell
Silicone will make rubber turn into a goo
Silicone and ordinary fluid will form a gel if mixed.
Silicone is a bit more compressible and give a softer feel to the pedal
Silicone is routinely used i NATO vehicles (which are stored for long periods) without modifications, no issues.
Silicone can produce adverse effects in an old car with old rubber quality, but not so in a reasonably new car
True? False? Anybody know? And by that, I do mean know?

All this said, I do admit that I have silicone fluid in my car, but as I said no crusader - just curious. The car is from 2004, changed to silicone (after thorough flushing) about four years ago, no issues. The person who persuaded me has a total of seven cars, ranging from a modern Tesla to a pre-war Nash and MG, a Volvo PV 1800, a couple of old Merc and a late 90ies +8. No issues on any of them. I admit this is anecdotica
Are we on a highway to hell? Or have my friend and I actually seen the light?

It's not Hydroscopic chaps

Hygroscopic = a substance tending to absorb moisture from the air.

Still confused but a higher level.... Has anybody actually experienced these detrimental effects of silicone? Of course they could be hidden down there somewhere, waitilng to surface. I do take notice of the air bubbles in a TR3 and the fluffy concrete on a Harley, but that is two... As an experiment, I have mixed silicone and glycol 50/50 in a glass. They separate in two layers when left alone, behaves like oil and water, but no gel. When agitated (shaken, not stirred) they mix, but still no gel. If this is transferable to the brake system I do not know, but FWIW that is what happens on my shelf. As for NATO, I find it surprising that NATO vehicles are stuck with something that puts the brake system at risk. It is silicone here in Norway too, can NATO really force the Norwegian military authorities (yes, we are NATO members) to use something that alledgedly has negative effects and may represent a traffic risk? Just wondering.
Finally, let me grab the opportunity to thank Lorne for a comprehensive answer (although I might differ here and there...) and for the splendid source that GoMog is. An obligatory read for every serious mogger!
