Why resort down to ad personam (the last two paragraphs)? These are not insults, but not valid arguments, either.
I know very well about Zerodium. However, FPGAs can be way more secure than any kind of ASICs. If you don't understand why, then I don't think further discussion is warranted. I worked with Apple's implementation of security enclaves, and they don't isolate (or "outsource" to be processed there) nearly as much as should be isolated. For example, whole display and touch input needs to go through the application processor, anyway. It's not a good way to go, to say the least. You can't overlay anything on the top of the display nor isolate touch input from some area (say, virtual keyboard) to go to the enclave. The rest of what it does is pretty meaningless, given these constraints.
