We know what a smartphone looks like and does. It’s not the fault of Tim Cook, but it’s not an area where there will be any more innovation.
The gods of technology (deus ex machina?) take offense when mere mortals make such statements. Remember when Microsoft was supposed to have a monopoly on computing? Or when we’d run out of oil? Or that other time we’d run out of oil?
If Thiel feels confident enough to declare that innovation in smartphones is dead, the gods of technology will prove him wrong. I look forward to the results.
