@OP. Maybe is my ignorance talking, or knowing that nothing intelligent comes from JF's mouth, but I believe the "predictive failure" can only work on certain electronic components due to self check algorithms.
The "predictive failure" on mechanical components is done the "old fashion way", by submitting the part to gruesome testing, mimicking the prolonged wear from normal use. Then, based on those results, the manufacturer recommends to swap the part at x-x miles, before it breaks.
Even with ten times more chips than ICE, an EV is more than a computer on wheels. Meaning there are more mechanical components than electronic, so the "predictive failure" feature will be very limited, by its own nature. Am I right?
So maybe this is another wishful thinking of BF/JF to dazzle investors?
As per JF's comments on talent at Ford, I must say that talent is already escaping through the front door. At this pace, Ford will get only deadwood and discontented workers. We'll see if hiring workforce outside of NA is really cheaper and better, or we'll end bringing contractors to actually do the work for us. I'd bet on the latter.
