why is it in a company's best interest to not evangelize the publicly-available tools it uses? Microsoft/Amazon/Google are paying $$$ to increase availability

  Two have told me they did so because D enabled them to write faster code than their competitors, and they were in a line of business where faster code meant making more money. One reason D code is faster is array slicing, where you can refer to a subsection of an array. This pays off for things like strings. Consider the string: s = "/root/me/file.ext"; I want to extract the "file" as a string. In C/C++, because strings are 0-terminated, I have a cache hit, allocate 5 bytes and copy 5 characters and install a 0. In D, name = s[9 .. 13]; I have no cache hit, add 9 to a pointer, copy 5 to the length. (A slice is equivalent to a (length, pointer) pair.)

  >why is it in a company's best interest to not evangelize the publicly-available tools it uses? Because they want people that are good with the tool, not people that crash-coursed/bootcamped their way into what they are told is a marketable skill.
