Every medication developed in the last 30 years, for starters. I mean, you're basically asking for a list of every invention derived from government-funded basic research (also known as "all basic research"). It might make more sense to ask what you could use.
I find it telling that you think it's challenging to name an invention that depends on any of the last 30 years of basic research, so we're at an impasse.
If I refrain from using anything invented and developed from government funding in the last 30 years, what would I have to give up?
