The purpose of software companies is to earn money not to give jobs to people who "want to code". Lots of people learned how to make games for NES, SNES, PS2, PS3, etc. All those machines are now obsolete. Current gen consoles are using x86 and ARM now and most upcoming AAA games are built on Unreal Engine. The competitive advantage of those who mastered coding for the Cell processor is gone. What should SONY have done instead? Should they still use the PS3 architecture in the current gen consoles to keep those developers employed?
