I must say the relative changes about the computing power of our devices today compared to yesterday. The first computer ENIAC was built in 1946 and consume in space of 1,800 square feet. Today, we have super computer in our hands called smartphones which can do far better things than first computer. According to studies if we compare this to ENIAC it is necessary to fill the entire america with ENIAC just to be equal in the computing power of our smartphones. How great is that? 😅
