Only another 8 years, eh? Does this assume a ceteris paribus scenario where Apple, Google, Visa, MC, PayPal stand still on infrastructure and mobile wallets?
I suspect that Apple, Google, visa, MC, and PayPal will continue to build bitcoin into their product.
Bitcoin does not compete at all with these companies. Just like the US dollar is not a competitor to Apple, visa, etc. these are products that incorporate currencies.
ApplePay is not a currency.
