The reason you have a computer that fits in your pocket, much less requires its own room with a reinforced floor is due to the NASA space program.

On edit: meant for the parent comment, but its parent instead

No. That's a common misconception. ICs were a commercial development, and microprocessors came from the calculator industry.

Pre-IC electronics miniaturization was pushed hard by the USAF; NASA just used it. The USAF had a flyable transistorized computer in 1954, before NASA existed. The Minuteman I missile (1962) carried a transistorized guidance computer.

Also Polaris, a little bit earlier (deployed 1960) had a very small transistorized guidance computer which was the design root of the Apollo Guidance Computer. Polaris was much more of a DDA (digital differential analyzer) than real computer though.

ICBM development is basically a space program with a different budget code though, right?

Yes, though there was a divergence later. For various strategic reasons you want your ICBMs to use solid rockets, so while the early manned rockets were liquid fueled ICBMs mated to capsules, money spent on ICBMs today probably doesn't do much for a civilian space program.

On the other hand, I doubt we spend much money upgrading our ICBMs. The technology is mature, and that's an area where "good enough" is, well, good enough.

And a delivery service too - "Your package delivered in 30 minutes or less or next one's free!"

(There at least used to be a Minuteman silo with the door painted like a pizza box with that slogan)
