Rare in new cars.  Go talk to the fuel injected TR-8 crowd and
ask them how often they fail.  I think, to me at least, the
problem with an ECU's is the question of restoration.  A carb
part can be machined and copied.  What do you do in 2027 when
you're trying to restore a 1990 whatever and you can't get
a .hex file?  Carbs seem so much more "fixable".  Of course
technology may change that, more aftermarket ECU's and so 
forth, but still...some metal carb bits could be made with a
file and some time...obsolete microprocessors aren't that
easy to copy.  $1000 will put a cheesy but usable milling
machine in your garage.  Somehow I doubt a couple of decades
of tech will bring the price of sub-micron lithography to such
affordable levels.

Very true, lack of understanding and frustration at authority
can cause such behaviour.

Again, I think they are better in only one way, the restoration
factor.  ECU's seem so "throw away" and consumeristic as opposed
to a carb.  I could see someone in the future (or even today, I
tried to talk the TR-8 guys out of a dead ECU) specializing in
restoring/updating "antique" ECU's.  

And, I'm still trying to a find an ECU for my Rover engine.  Plenty
of aftermarket carbs out there for it, but the only ECU's I've
been able to find are new, for $450, which is to me way too much
for an 8-bit processor and some EPROM.
