When my kids talk about SpaceX or Blue Origin, I tell them in our day they did it with stuff designed with slide rules, drawn with pencil on mylar, and fabricated by high school grads on manually controlled machine tools.
I have a few slide rules. I pull them out once in a while.
with the exponential technology increase we have had since the 60’s and the same increase in the available money supply
It almost makes one wonder if humans have ever really walked on the moon and came back to talk about it.
