I believe you're misreading the breakdown - I read that as "23% of budget goes to personnel costs, which include paychecks (for active duty), healthcare (for military and their dependents until 26), and retirement for vets"
I fully believe that only 5% of the budget goes to Veterans Affairs, at least in the US. The system is not very good at taking care of vets/
>Those breakthroughs you mention, you think they wouldn't have been made if it wasn't for the military? Some of those things are also borderline not invented by the military at all, but lets disregard that for now.
The list:
>>rockets, jets, computers, encryption, RADAR, SONAR, internets, canning/food preservation, weather prediction
* Rockets are an entirely military invention - the Hargrave rocket invented for the British Royal Navy in the Napoleonic Wars, the chinese pseudo-rockets used as artillery, the V2 rocket used in WW2 Germany, etc. I think one of the only non-military rocket scientists known to history is Goddard.
* Jets - also an entirely military invention. I'm assuming you mean "jet air craft" here - WW2 was the first use of jets to power an airplane. The Soviets and Americans quickly followed suit.
* Encryption - encryption has been in use in militaries since at least the roman era; another name for a substitution cypher is a "Ceaser Cypher." To be fair, this isn't exclusive to military use, as states have an interest in keeping their communications secure, as do banks, but in terms of "money invested in development of cryptography as we know it," the field was effectively invented whole hog during WW2 (again), as (military led and funded) analysis of how codes could be broken lead to the need for new encryption methods that were more secure. See also: the NSA. (note - I'm being sloppy with codes/cyphers/encryption here)
* RADAR/SONAR - literally developed during WW2 by the British using US funds in order to detect submarines and the Luftwaffe terror attacks. The germans had a very sophisticated RADAR tech at the beginning of the war (directed radar for night defense), but failed to develop it any further.
* Internets - the internet, as a system of interconnected computer networks, was funded by ARPA/DARPA, the DEFENSE Advanced Research Projects Agency. ARPA-net was first used by the Pentagon. Pretty much the entire US software and hardware industry was built off of US defense contracting, and this is no exception.
* Canning/Food preservation - the biggest advances in canning/food preservation were the result of studies/competitions funded by the British Royal Navy in the 18/19th centuries. The British defense industry funded the development of canned goods as we understand them today. Interestingly, this is where a lot of our understanding about vitamins started to be learned by (heavy) trial and error, as the RN tried to figure out how to combat scurvy.
* Weather prediction - meteorology as a science got tons of money from (you guessed it) the British Royal Navy, who understandable wanted to better predict conditions for their large navy that was made of wood and canvas. in the 20th century, meteorology got huge infusions of cash from the USAF, because planes care about weather and storms to a huge degree. This was a scientific field outside of the military, but even then, it was a matter of State security to predict the weather so you could understand crop growth patterns etc.
So, to answer your question, no, I don't believe any of those technologies would have developed organically.
