Not obsolete , but like females , I see them changing to suit a new environment in the future . Once upon a time the general path for a male was to be born , go to school , then get a job and have some fun with friends , meet a girl and fall in love , knuckle down A the job focusing on making more money to support the family . Work 50 years at that putting the needs of the family first and then hopefully retire , quite worn out but with the satisfaction that they have fulfilled their role .
With relationships changing the male may evolve to be more selfish and focussed on what they want out of there own life .
So end result , with females quite rightly wanting to be more independent and wanting control of their lives , eventually the male role will change and they won't be so keen on signing up for family life .
I still think that if you sweep away the more vocal views on relationships you will still find a core of our society who still feel comfortable with traditional roles of the male and female so it will be a while before there is a total change to roles .
