I couldn’t agree more.
And I can only reiterate, with my initial comment I was not attacking you personally or trying to guilt you into doing something. I also don’t like when people do that. In fact, it wasn’t even that much about saving water in the shower. It is just this blocking attitude of: I don’t do it, others should start first without even thinking about it, that you can often read in these threads which bugged me at first.
By your comments you showed that you actually thought about it and came to the conclusion that the impact is little and there are more important topics you want to address, which is a totally fair point.
You only need industrial robots if you produce something. Since a majority of production is outsourced to Asia they have a much higher demand for robots.
