@kas1e I’m pretty sure he wrote somewhere that development time was shorter it is more a combination of ObjC and the framework than the language itself.
It is known that NextStep and now OSX made it possible for a single developer or a small team to deliver apps faster and be able to be competitive against big companies. (See pimp my code by Will Shipley) of course MorphOS framework is not on par with nexstep/ISX but it’ll grow.
