Now if this was based on the quality of Cooks ability to lead Apple, I would simply say they haven't had a huge hit since Apple Watch some 10 years ago. Cruising nicely in terms of sales and incremental improvements but nothing that has others desperately chasing them.
I would say the first laptops with Apple Silicon were a huge hit. They’re from 2020.
For example, I have questioned why Nvidia has been able to be the unchallenged leader in AI graphics cards.
With Apple's silicon knowledge, access to leading edge TSMC fabs and volume purchasing power (due to selling millions of devices) – Apple could and perhaps should be selling unique processors to AI companies, and also using them themselves – taking a huge amount of revenue and mindshare from Nvidia.
