I know, imagining things is hard. But that's not much evidence either way.

Yes, there might be some government programs that look like a good deal in retrospect. Just like some lottery tickets are winners.

The heavy press program even turned a profit, if I remember right. Though private enterprise is usually pretty good at funding these kinds of projects, even with long lead times. (See eg how Amazon or Tesla or even Microsoft took ages to return capital to investors, but still had enthusiastic shareholders.)

I don't know specifically about packet switching, but you hear similar arguments about the invention of the computer.

In our reality, programmable electronic computers owe a lot to government and specifically military funding. But as a thought exercise, perhaps you can imagine an alternative history without WW2: IBM already made computing devices for business long before the war, and it's relatively easy to see how they would have eventually come up with a programmable electronic computer.

Compare also Konrad Zuse's work in Germany:

> After graduation, Zuse worked for the Ford Motor Company, using his artistic skills in the design of advertisements.[14] He started work as a design engineer at the Henschel aircraft factory in Schönefeld near Berlin. This required the performance of many routine calculations by hand, leading him to theorize and plan a way of doing them by machine.[21]

> Beginning in 1935, he experimented in the construction of computers in his parents' flat on Wrangelstraße 38, moving with them into their new flat on Methfesselstraße 10, the street leading up the Kreuzberg, Berlin.[22]: 418 Working in his parents' apartment in 1936, he produced his first attempt, the Z1, a floating-point binary mechanical calculator with limited programmability, reading instructions from a perforated 35 mm film.[14]

> In 1937, Zuse submitted two patents that anticipated a von Neumann architecture. In 1938, he finished the Z1 which contained some 30,000 metal parts and never worked well due to insufficient mechanical precision. On 30 January 1944, the Z1 and its original blueprints were destroyed with his parents' flat and many neighbouring buildings by a British air raid in World War II.[22]: 426

> Zuse completed his work entirely independently of other leading computer scientists and mathematicians of his day. Between 1936 and 1945, he was in near-total intellectual isolation.[23]

In our real history, the US and UK armed forces came first, but a world with more resources in the hands of the private sector (and also with less war) would have surely accelerated some of these private computing experiments (IBM or Konrad Zuse or someone else), and we would have seen computers at roughly the same time as in ours, or perhaps even sooner.

Similarly, the real history of packet switching is heavily intertwined with some US government projects. But even just browsing Wikipedia https://en.wikipedia.org/wiki/Packet_switching tells you about other attempts and projects going on around the same time. So the government's investment probably did not speed up things by that much, even before you consider that in our counter-factual the private sector would have more resources.
