Making a smart computer is easy
AFAIK, the only documented way to make a smart computer has a production time of nine months of trouble. The programming is a pain that literally takes work years for each.
I have never heard anyone call that process easy.
if I wanted to do space, I'd just buy NASA
You might want to check track records for delivery times and cost overruns before doing that.
I think you will have a hard time finding any organization that has missed cost estimates as much as NASA did for launch to orbit, literally orders of magnitude (they promised hundreds of dollars/lbs for the shuttle, think it is about 10,000... :-( )
