It looks like Apple might be re-assessing their R&D expenditures to reduce spending.
This is it right here!
Think of when Steve Jobs came back and started slashing things that didn't make money or sense to him. Apple is starting with some of the largest expenses that don't directly relate to what they are able to sell or make money on and cutting back. Which they should do. If all of a sudden people stop buying products etc. Apple needs to be ready for that.
Economy thinking is what all these cuts are about. No more throwing money on things that are not actually necessary right now.
MicroLED and the Car project are the first to get the axe but there will be others. Those have been very long projects that don't have any immediate benefit going forward. Take what they did produce and put that into products you can ship, is where I think this is going.
