This is also a thing I think we don't explain very well, because a frequent response is "oh those things would've been invented anyway" (with the implication they would've been invented more cheaply).
Which is not how it works.
The cost of the actual raw materials to build almost anything is a tiny tiny tiny 1% fraction of the cost of what the thing actually costs to build. Rocket fuel, titanium etc. are all cheap compared to the cost of actual rockets. So the question of course is, where does all that extra money though? And the answer of course is: into people, process and technology.
The cost of rocketry, or particle accelerators or fundamental science, is correctly viewed as a massive sponsorship and investment into people and tools to improve how they do something so they can do it better.
And that is why "spin-off technology" actually happens in the first place - because large projects mean that we have now skilled up, tooled up and improved the capability of vast numbers of people, companies and fields of trade - which is what makes new innovations possible, or changes the market dynamics so things become economical and then profitable.
