Any new computing solution is going to surprise us all,I think.
Historically every new tchnology has many people starting new companies or divisions to produce their version of the new wonder. At one time the U.S. had over a hundred automobile makers,then a couple dozen,then only a handful. Likewise home computers began with tinkerers then dozens of companies ,each promoting similar but incompatible hardware/software. Several early platforms of great technical merit fell through poor marketing or management blunders.
Ultimately,every product category,from automobiles to clothing, seems to mature with several huge companies dominating that market for mass production with numerous specialty companies serving those who want that item/product in a special regional/low-fat/high-performance/customized/personalized/organic/ or in some other way different version.Think boutique or niche markets
Seldom does the mass market item embody the characteristics valued by enthusiasts.
I can't see how the Amiga or AmigaOS will ever be other than a niche market especially in view of the decisions by every company that has held the commercial rights.All the wounds to Amiga have been self-inflicted.It really deserves a chapter in "Out of the Jaws of Victory".
