If it gets to asics for btc mining it will be 2018 or later. Right now the money is not there for asic's.
14m are mined 7m are left (rounding) by 2018 maybe 5 million left.
so
5 million at 100 bucks = 500million no need to advance mining in any way
5 million at 1000 bucks = 5 billion well we may have the need to do 16nm or 14nm but 10nm and 7nm still not $$ worth it.
5 million at 10,000 bucks = 50 billion 16nm 14nm and 10nm will all be developed and pressure for 7nm will be strong.
All pulled out of thin air by feel for it to be true.
