program controlled computer and 30 years later for the same price we could do 1 million times as many operations per second because he could do only one operation per second roughly and now it's 75 years later we can do roughly a million billion instructions per second for the same price and it's not clear that this trend is going to break soon because the physical limits are much further out there if this trend doesn't break then within the near future we are going for the first time we are going to have little computational devices that
