Production problems show almost immediately, even if there is only one
person. And they show after making let's say 20 units. I.e. it does not need
to produce let's say 1000 units to find real production problems. And if
you produce 1000 and find that 5 are bad, you don't worry as much as
if you have 2 bad in 20.

Of course it can. It is a matter of calculation.

That is a dream that is not realistic. Every display has a different connector
(there is no standardization!). And every CPU has different signals and
power supply needs. I.e. you can swap an OMAP3505 for an OMAP3530
or an DM3730 but nor for an OMAP4 or OMAP5 or Snapdragon or i.MX6.
Because they are not designed for this way of use.

Yes but I have no idea how this could happen.
