Earlier quoted context omitted.
Apple managed to design its own state-of-the-art CPUs. I wouldn't have imagined that designing its own modem would be such a difficult challenge?
Except making a decent modem is indeed harder than start of art CPU. People loves to shit on Qualcomm but dont appreciate that amount of work involved.
The hard part is designing a good modem while also unambiguously working around all the Qualcomm patents in all the jurisdictions that have iPhone, which is all of them.
Because if you don’t do that, you’re still paying Qualcomm which defeats an important purpose of making your own modem.
