Interesting book, however any tech newbie reader would be forgiven for believing that digital technology starts and ends in the USA.

Am currently on page 209, more than half-way, and the only non-USA programmer/techie you mention is Ada Lovelace, and she was Victorian-age British mathematician.

Where is your background info about people such as Alan Turing at GC&CS Bletchley Park - UK, first people to use a computer, called 'Colossus' to break German Enigma codes during wartime, and heavily dependent on people that could well be considered 'Coders' for programming Colossus rather than 'code-breakers' overall. ENIAC was not the worlds first digital electronic computer.

If you interviewed students on university campuses in computer science courses, and Coders in industry, outside of the USA you would receive varying and more rounded feedback, and your very interesting book would sell more copies outside the USA.

On the positive feedback side, your 'Coders' book has led me to become more involved in computer science again.

Hope you are interested in updating your book to cover a broader view of the tech industry on a global basis.
