> Not everything hits mass market in a 5 years timeframe... in the short term it may seem we have a slow rate of adoption of new technologies, but if you take a step back you can see the rate is fabulous. Graphene, batteries, solar cells and before them, transistors, nuclear power, etc. may take a while to hit the market, when they hit it they hit it hard. Most of those older comparisons still aren't flattering to graphene. We're nearly 15 years away from Geim and Novoselov's Sellotape trick now. 14 years after the first working laser in 1960 (though the first maser was in '53 and apparently the first paper was '51) the first supermarket barcode scanner was in operation, while Xerox PARC already had a working laser printer system. The first transistor was late 1947: the first consumer transistor radio was 1954 https://en.wikipedia.org/wiki/Regency_TR-1 https://en.wikipedia.org/wiki/Regency_TR-1 , and the US military had been using transistors well before that. Calder Hill nuclear power station (see https://en.wikipedia.org/wiki/Sellafield https://en.wikipedia.org/wiki/Sellafield ) opened in 1956, about 14 years after the Manhattan Project and Chicago Pile-1.
