It will never replace Linux on invisible devices, but on consumer facing devices with a screen (ie. car info systems, heck even possibly an Android competitor).

It will never replace Linux on invisible devices, but on consumer facing devices with a screen (ie. car info systems, heck even possibly an Android competitor). First of all, there is no GPL, second its an integrated system with a single path from kernel to any component so makes customising easier, third the design emphasis is on latency not throughput (so great for GUI but not for file serving). If Haiku was available in 2004, Playstation 3 would be Haiku based (not FreeBSD based), and Android would have also been Haiku based. Google are working on Fuschia to replace Linux in Android, whose core development team are ex BeOS engineers who built the kernel Haiku is based on and there is talk of Fuschia adopting BeFS from Haiku.
