Frankly, while there are still lots of things I love with AmigaOS and miss in Linux, this is a downright ridiculous statement to make. It takes a *huge* amount of tweaks to AmigaOS to get a system that is anywhere near as usable as most modern Linux distro's, and you'll still have huge holes.
Linux with its monolithic kernel seems to be the past. It's nowhere as extensible as AmigaOS was in its first day. Any BSD seems much more evolved and advanced than Linux, at least in extensibility.
The rest of the OS (GNU) is not my cup of tea, starting from the lack of coherence between its parts (core and GUI) and all the heterogeneous and badly integrated apps.
Already in '89 or so while using AmigaOS extensively, my system was tweaked beyond recognition to get to the experience I enjoyed, and it was still in most ways substantially inferior to most modern Linux distros.
Linux is slow, no matter what you do. Any AmigaOS flavour runs rings in terms of speed.
All the rest of OSes: OSX, Windows, BeOS... are far more integrated, intuitive and usually faster.
Invest the same effort in tweaking a Linux distribution now, and you end up with something vastly more polished. And if you like you could end up with something substantially closer to an Amiga experience.
AmigaOS flavours are already enjoyable out of the box, these are already fast, no need to waste hours tweaking them like Linux.
Amigans enjoy tweaking their systems but it's not mandatory at all.
the pale in comparison to the features that are lacking, such as proper memory protection and full support for virtualization (I have a dozen or so lightweight virtual machines running on my home machine) or full fledged package management.
Android apps suddenly die and leave your phone frozen and you have to reboot it. It's funny because Android devices are the perfect example of Linux: these require incredible high amounts of resources to do stuff that would work much better on AmigaOS. And memory protected or not Android apps crash and slow down your phone so much that you have to reboot it. I have to reboot phones with "memory protection" much more often than I have to reboot AmigaOS flavours just for the simple fact that Linux is coded like memory was infinite and never exhausted.
I'd love to be able to use a more Amiga-ish OS as my main OS, but before that can happen, either AROS or AmigaOS would need to take a lot *more* stuff from Unix/Linux, or more Amiga-like features would need to be ported to Linux; there's no way I'd be able to go give up all the things I've come to expect in an OS after using Linux.
Most of stuff that comes with these OSes that take gigabytes of space is rubbish or are 14 outdated GUIs for a cli tool that got recently updated and crashes and burns.
All in all: when Linux crashes and burns you always end up having to edit weird config files located at random paths, instead of having a GUI emergency boot that boots with basic VGA modes and 640x480 I guess it's much more intuitive for these bearded kernel hackers.
(I say *more* stuff would need to be taken from Unix/Linux, because already with the first handful of Fish disks in the 80's we were getting a steady stream of Unix ports)
If I wanted to run all that GNU apps I would run them on a unix environment (but a more modern one that use microkernel, not a monolithicly obsolete one like Linux).
Monolithic kernels are so 70s...
