I think one of the most interesting times to be in electronics would be the roughly 25 years from the end of WW II through the Apollo era. That time saw the birth of the transistor and microelectronics, the rapid growth of consumer electronics and broadcasting that had been on hold during the war, the development of modern computers. missiles and space exploration, and the widespread commercial deployment of technologies developed during the war such as atomic power, radar, microwave communications and jet aircraft.
