My new iPhone symbolises stagnation, not innovation – and a similar fate awaits AI John Naughton

I bought an iPhone 15 the other day to replace my five-year-old iPhone 11. The phone is powered by the new A17 Pro chip and has a terabyte of data storage and accordingly was eye-wateringly expensive. I had, of course, finely honed rationales for splashing out on such a scale. I've always had a policy of writing only about kit that I buy with my own money (no freebies from tech companies), for example. The fancy A17 processor is needed to run the new "AI" stuff that Apple is promising to launch soon; the phone has a significantly better camera than my old handset had – which matters (to me) because my Substack blog goes out three times a week and I provide a new photograph for each edition; and, finally, a friend whose ancient iPhone is on its last legs might appreciate an iPhone 11 in good nick.
