certainly things change and no one ever stays dominant forever so i see this period coming to an end. 5-6 year periods seem to be the norm or was for RB and Ferrari before them.
will they dominate again?
personally i hope the cost cutting/budget cap systems works and leads to a more competitive era where no one team dominates.
that said the Patriots are an interesting reference as they have created a dynasty during a period of salary caps and league parity, equalization of league revenues etc - making what the Pats do much more impressive.
but maybe bigger question is do Merc still fund/prioritize their F1 program at a maximum level after LH retires?
and at some point you think their budget priorities will shift to FE?
so another question is if there will be any point (mass marketing/mainstream/advanced technology) in dominating F1 in the mid to long term future?
