These two statements could be section headers in a valuable article - or
book chapter.

The problem with the standard VM concep: it takes the metaphor of separate
computers too literally. The potential for lessening the materials expense
and environmental cost of producing so much hardware and the electricity to
power it - is huge. Conversion to containers instead of VMs can be a major
economic win.

But only if the knowledge of how to do it becomes widespread.
