It's only a fraction of the CPU's power, sure, but it's still consuming power (electricity & processing) without actually doing anything, which is wasteful. And every small inefficiency adds up over the scale of everything.
> Perhaps but this thread and discussion might add up to a year's worth of that waste.
Don’t forget about the number of macOS users. A lazy search says ~100 million in 2017.
Apple talks a lot about their environmental impact, they spent like 10% of their last event talking about it. So I think it’s fair to criticize them being wasteful here.
in this example it's showing the seconds on the clock, which might be useful to some. (Just pointing out that using < 0.1% of the total CPU (depending on how you'd weight the efficiency cores) should not be a dealbreaker if you like this feature)
