Excellent rant, I am in violent agreement.  But this 'failure' goes back a 
long ways, even past what little time I spent in school back in the '40's.  
The one size fits all, dumb it down to the lowest common level that 85% can 
pass theory was in full bloom by 1948 and is part of the reason I quit and 
went out to fix these then newfangled TV sets for a living, but switched to 
broadcast in '62, and was the CE at WDTV-5 from 1984 to mid 2002 when I 
retired.  But I was good at it, and my phone still brings me work yet.  
FWIW I am also a C.E.T.

Well, I was hoping that George Ramsower would check in, he is using a coco2 
to drive the cnc mill he is carving steam engine parts with.

ATM, an elderly (1.6 Ghz athlon) PC is running EMC, which is driving a 4 
axis xylotek driver and that is running the machine very well.  In fact I 
made 2 steel bars today, with 1.003" diameter recesses .060" deep to 
contain the ends of a pair of tubular rails that a sled holding my planers 
blades slides back and forth on for 3 feet, and am redoing the mounting of 
this assembly to a Grizzly wet wheel that turns horizontally with the wheel 
facing up.  The wheel is a rouge rated at about 12,000 grit, runs with a 
dribble of water running across the face, and it is this face that the sled 
holding the blade to be sharpened runs back and forth over.  You have not 
seen a sharp blade until you've seen a blade sharpened on one of these.  
Wet, even at 12,000 grit, it is a cutting fool, and leaves a surface so 
polished you can use it for a shaving mirror.  Well polished edges are also 
sturdy edges, staying sharp 3 or 4 times longer.

But now we are truly off topic.  Yes George is using a coco2 for cnc, but I 
could do what he is doing in 5% of the time the coco2 takes.

Cheers, gene
