Why poison text?

No. If people are coding, over whatever amount of time, they're using energy at whatever rate these massively wasteful racks of GPUs consume. kWh is a (slightly odd) unit of energy, the integral of W over a specified period of time. Over unspecified, whatever amounts of time, we can't give an amount of energy used, but we can talk about a rate.

If you wanted to use kWh, you'd have to change my comment to something like "requiring several racks worth of expensive silicon and 800+ kWhs of power per "vibe dev" per day". But... why do that? Just divide the terms in that sentence by 'day', and the "per day" disappears, as does the 'h' in kWh. Or another way: Why pick 'per day'? Why not per week? Or per month? Or per hour? or ....

Better still, instead of doing "X energy per second per hour for each vibe dev per day" - which is just obviously silly in terms of all the units of time being multiplied and divided - just get rid of the extra, redundant additions of time and just say "X energy per second", i.e. W. ;)
