I think we have several different questions here.
What is Amiga in 2012?
What would have been Amiga in 2012 if Commodore hadn't gone out of business?
What should carry the Amiga name?
What could the Amiga be in 2022?
For me I love playing with AOS, it reminds me of the days when I first started with computers, the days when your phone, tv and refrigerator weren't part computer. A large percentage of computer users weren't just users, they were also experimenters and tinkerers.
Computers nowadays are appliances, the vast majority of users are just users. Computers entertain but they don't really engage us anymore. Technology has advanced to the point I can't possibly fathom what's going on inside the computer or all the bits that make it work. Operating systems go to great lengths to hide that complexity.
The old Amigas are like flying a b-plane instead of an A380. On an Amiga bugs get in your teeth, and you are far more likely to crash. You are going to have to actually control the machine and not trust the levels of software between you and the hardware. It'll get you there but you are going to feel the journey, every air pocket and downdraft. The journey will be longer, harder, but the sense of accomplishment at the end will be far greater.
Oh, who am I kidding, just load up the game already....
