Yes, but some architectures are better than others, despite all having
benefits and weaknesses (of course everyone has differing opinions on
which ones are better). Would you like to replace your modern
multitasking OS with CP/M or DOS 3.3 - after all everything has
strengths and weaknesses? It depends on what you want to do with the
OS. So what are microkernels well suited for as compared to monolithic
systems? In what cases would you opt for one over the other?
