> It amazes me the amount of engineers who can use a tool every day yet remain not the least bit curious to its basic internal operation. And how many of them use word processors and/or spreadsheets and don't bother learning about the internal structures of file formats? * https://en.wikipedia.org/wiki/Microsoft_Office_XML_formats https://en.wikipedia.org/wiki/Microsoft_Office_XML_formats Have you ever examined the bitstream of gzip or the structure of tar, even if you downloaded source file in them? Do you know the structure of RPM and/or Deb packages (depending on your favourite distro)? Do you know the voltage pattern of the Ethernet signals that go down the cable (or waveform of the Wifi / LTE radio signal)? There are only so many hours in the day, and not everyone wants to (or has the time) to go deep into every rabbit hole.
