Right but it still gets put into boxes and flown over by a 747. Of course it‘s more complicated than that, but most contenders for complex machines are much more built in-place, and not a complete 'product' being assembled.
I‘d probably call it the most complex commercially available machine. You can‘t buy a Space Shuttle, or an LHC. You can buy a TSMC lithography machine, and it‘ll be delivered to you in much the same way as other equipment.
Also, I think the axis it‘s probably most complex on is precision of individual parts and of their combination. Arguably chips themselves are more precise as their 'parts' are so small, but they are much more homogeneous compared to the EUV machine, where tons of different materials and part sizes need to combine.
I can‘t imagine Apple doesn‘t have capacity booked well in advance, and their suppliers aren‘t going to stiff them because they‘d lose those long-term contracts. Sure, if the shortage lasts a year or more, there‘ll be issues, but if it‘s short term they might be fine.
Too expensive maybe, or just not effective anymore as they used up any available training data. New data is generated slowly, and is massively poisoned with AI generated data, so it might be useless.
