I didn't say it's old-fashioned, it does the job given in the US cars are not taxed based on displacement. Rather, to claim DOHC engines with variable lift and variable cam phasing produce "limp wristed engines" is illogical because General Motors themselves use DOHC in all their other engines!

General Motors' own 4 cylinder turbo engine has DOHC:


General Motors' own 4.2L 8 cylinder hot vee twin-turbo has DOHC:


Clearly DOHC and variable valve timing paired with smaller displacement and (potentially) turbochargers is a good engineering solution for the vast majority of purposes.
