Hi Carol

While I accepted the article's slant, it crossed my mind (again)
that mainstream science has a history of making complacent
assumptions and over-valuing modern human achievements; causing
misapprehensions which sometimes persist for generations.

Maybe some large or small phenomena now classed as 'natural' -
even big stuff like quasars, magnetars etc. - might be higher
Kardashev civilizations' engineering or power generation works?
