What will happen:
Self driving cars and electric cars will have been introduced into the mainstream, motorways will probably start changing to adapt
Severely increased unemployment due to increasing use of robots - admin, retail, cafes/restaurants, cleaning, taxis, etc.
Families living together longer because there won't be enough housing and it will be too expensive
Tightened immigration
Increasing education means increasing competition for 'skilled work' - gaining meaningful employment will just become tougher and tougher
Increased tolerance of homosexuality and other related issues
What won't happen (only retards would believe these):
London becomes independent state
Muslim / Islamic takover
