I work in the IT industry, so of course I have heard the term clock speed in relation to how fast the processor in a computer goes. Nerdy perhaps, but perfectly acceptable. However, lately I have been hearing it more and more in relation to people, as in:
Jane has a very high clock speed.
What they really mean is that Jane is very productive or a quick worker. I dislike it because it’s another way of referring to people as an inanimate object, a resource or product, like ‘human resources’ and ‘alignment‘.
