So y'all went to to the moon with this technology in the 60's but can't go "back to the moon" in the 2000's? Even though the 60's technology is now available on a cell phone? 👀. Please explain...

Computer scientist Margaret Hamilton photographed in 1969 standing next to the Apollo guidance software that she and her MIT team produced that sent humans to the moon. Hamilton led the Software Engineering Division of the MIT Instrumentation Laboratory, which in 1961 contracted with NASA to develop the Apollo program’s guidance system. Credit:
