I do not want to be ironic, of course, but I have the impression that we first replaced the
venerable"( ph -> A. x ph)" by" F/ x ph" supposed to be more meaningful and that now
to put in common factor some parts of the proofs we reintroduce"( ph -> A. x ph)"
beside" F/ x ph" finally returning to the previous state and multiplying the proofs by two.
And we hope to fight against ecological disaster.
This civilization will die crushed under its own weight.
(By the way "Google Translate" may I recall Thee that the translation of the
French word "démonstration" is "proof" not "demonstration". Please !)
