I guess it might be because the nature of your work. When I started as a SE over a decade ago, my job was really just writing code according to the specs. Typing speed was important as I wrote over 100k lines of code in the very first year. But less and less code I wrote after that. Once I spent around 6 months meeting CEO daily just to figure out what was wrong with something screwed pretty badly by someone with a fancy big title. Eventually the code I changed to fix those problems were less than 30 lines. That was extreme, but on average, I hardly write more than 100 lines of code per day just like you. Typing was no more an issue for a very long time.
