Apple has had the best operations people in the business since the iPhone came out.... well, scratch that, they had the best LOGISTICS people in the business since the iPhone came out.
But since Jobs died, there is no one in the company running around driving any real innovation. The saving grace has been that no other tech company does either, but people expect more from Apple. They need a benevolent dictator running around telling people they suck or they are great and get new products and applications in place. Phones are pretty much maxed out for function, and embedded technologies are likely the next frontier with AI as the governing tech behind it, and by all accounts Apple blew their development, though none of is know why.
The book Apple in China was really, really interesting. While it focused on Apple, it showed how the US and all tech companies were totally played by Xi and the Chinese. China now no longer needs us - we handed them tech and processes that let them skip 20 years of R&D, all at the companies' and Americans' expense.
I think shedding these strata of execs are a reflection of that... but I also do not see any actual creative force in the company. I've been a stockholder for 20+ years and I am wondering if it is time to start phasing out.
