Great read. I just wanted to add some clarity about the Hedy Lamarr part. Twenty-five years ago, I wrote an article for c|net about Hedy Lamarr's contribution. She developed the frequency-hopping spread spectrum technology alongside George Antheil and they patented it in 1942. The Navy categorized the idea as "red hot" , but were a bit leery about applying it, not because she was a woman, but because the idea was developed outside the Navy by foreign nationals. (She didn't become a US citizen until 1953). It was known from the beginning that she and Antheil were responsible. She was even interviewed in Stars and Stripes about it during WWII. The Navy applied their technology to one project before the patent expired in 1959. It wasn't until the technology was applied to Bluetooth that she really began to be celebrated for it, which makes sense because its relevance tor the average person was more obvious.
