This is such a silly technical argument that I’ve seen twice now in this thread. Watts is just Joules/second. It’s entirely valid to wonder “what rate am I ‘consuming’ energy when I do X” rather than ask “how much energy did I ‘consume’ when I do X”
Making this correction is similar to telling someone that asking how fast they moved is wrong, and they should only ask how far they moved.
It’s not about the content, but rather the skills gained when becoming an expert on the content. For example, physics degrees are often sought after in the financial realm because of they’re expert ability to model things with mathematics.
Philosophers are generally expert thinkers, writers, and debaters. Not a lot of jobs are hiring philosophers for their content knowledge, but instead, they’re hired for their skills.
