I remember the 3090 (trout 1.5) processor engineers saying something
similar ... that they had optimized memory and floating point ... so
that floating point operations were happening as fast as memory could
deliver data. vector operations couldn't go any faster ... since memory
wouldn't be able to deliver data any faster (slightly different
argument).

there was conjecture was that marketing believed that there were
customers that would buy "vectors" ... just because it said "vectors"
(assumption that individual floating point was so much slower than
memory ... that memory was able to keep up with multiple floating point
units running in parallel).

as soon as Future System failed 
http://www.garlic.com/~lynn/submain.html#futuresys
... two teams were kicked off in parallel, ... one was doing quick&dirty
303x in parallel with 370/xa&3081
http://www.jfsowa.com/computer/memo125.htm

as soon as 303x was done, that team started on 3090 in parallel with the
continued 3081 activity.
