Apple's revenue numbers the past 15 months really seem to conflict with management's statements that their staff needs to be in-office in order to produce optimal results.
Revenue numbers at time T are often the result of work done at T-3 years, T-2 years, T-1 year etc
Yes, everyone went into remote work with a lot of momentum. It will very interesting to compare something like the iPhone 14/15 with previous deltas. But even more so, I think the new product lines and early stage products will take the biggest hit to their schedule.
I think this means that Apple's profits don't depend on its staff, at least this is what top management believes in.
