I feel similar, I was a Linux Sysadmin in the early days of Gentoo, studied C and Network programming, configured hardware and RAID arrays and did some courses like "From NAND to Tetris". Over the years I did a LOT of programming. When "the cloud" came out, I could easily understand the magic behind it all, so it made a lot of sense to me and it still does. I feel "computer literate", however, even a lot of solid but younger engineers I work with struggle with lower level concepts and just don't have the knowledge and experience with things like networking protocols to be able to solve hard problems.
