The corporations might start taking crypto here shortly...but that is a side issue. How to get paid isnt really their problem...it is blockchain. In fact, many are expecting a big announcement by Amazon in the beginning of February regarding BTC and ETH (it got the domain names from what I read).
In the end, with DAOs coming on-line in the next few years, you will see the traditional corporation hit...many industries will feel the power of blockchain....some will benefit, others will be destroyed.
