The number of doctors is irrelevant. The point is that some things are worth far, far more than a single extra 0.

I would give 1000 hours of my time to a surgeon if it meant they saved the life of my partner. I don’t care if it only took them 60 seconds.

Some things are far, far more valuable than a single extra 0.

Heat pumps move heat around, whereas radiators create it.

The “efficiency” of heatpumps relates to heat they import into a system for a given amount of power, compared to creating heat with that power. They are not generating that heat. They are moving it.

Similarly, it’s much more energy efficient to use a wheelbarrow to collect ice and move it inside, than it is to make ice cubes in freezer.

This is why I use Linux, the fingerprint device wouldn’t be supported so this wouldn’t be an issue /s
