It is hard to imagine anyone but Uncle Sam building the first computers. Or
highways, or the Transcontinental Railroad. Or project Whirlwind.

Transistors, on the other hand, would probably have taken off their own.
Setting up a transistor production line was cheap. As I said, most
transistors were initially more expensive than the vacuum tubes they
replaced. Some of them far more expensive. But even at a high cost
transistors still had a niche markets in civilian applications, such as
hearing aids. Hearing aids were among the first product made with them,
although I think it was at no profit, as a public service. They soon began
making small portable radios, which sold at a premium.

The prices soon fell.

Transistors would have taken off, but it would taken many years longer. You
cannot run history over again, so it is hard to say how much longer. The
point is, cold war weapons and the space race produced hot-house growth. As
I said, a whole new type of fast memory chips were developed for the LARC
computer. Two LARC computers were constructed. The chips were obsolete and
never used for anything else. This is like developing a iPad, selling 100
of them, and then junking the design and starting over again with a
different display technology. It is economic lunacy. But it sure pushed the
technology along quickly!

I have an article written in 1969 with a long list of major computer design
innovations developed or advanced for the LARC, such as instruction overlap
and hardware modularity.

Project like LARC not only advanced the state of art at high speed, they
also trained a large fraction of the people who designed and built
computers in private industry for the next 20 years. I have heard that just
about everyone in the business in the 1960s got started at MIT Whirlwind or
SAGE.

MIT Whirlwind at the time appeared to be a black hole of expenses. It went
on for year after year, swallowing up millions of dollars (in 1950s money)
where only a few hundred thousand were initially budgeted. It seemed to
produce nothing. It was classic example of an Air Force project gone
bonkers. Then, as it wound down, it spun off CPU designs, core memory
thousands of times faster, cheaper and more reliable than anything
previously developed, orders of magnitude faster processing, the SAGE
computer, and host of other things. Just one of those breakthroughs would
have paid for the whole thing.

As I recall, it never actually achieved the initial goal, which was to make
a flight simulator for WWII. It began in 1945 and run until 1953 -- way
behind schedule, and WAY over budget. In retrospect, that does not matter.
