Here what he said:
"I used to build some pretty mean LEGO towers when I was a kid,” the president told an audience of mostly Intel employees. I thought I could participate, only these students used their LEGO’s to build models, to build robots that were programmable, to model brains that could repair broken bones.”
The crowd erupted in laughter when the president, seemingly exasperated joked “so I guess that’s different than towers.”
There were some times where not even the President knows what people are talking about.
It was a sobering experience for the Harvard educated leader of the free world. Young people, the ages of his two daughters Sasha and Malia, talking “about things like quantum ternary algorithms,” the president said then added “it gave me a chance to nod my head and pretend that I understood what they were talking about.”
So no matter how old you are there are still things to be learnt.
