Query: The paradox of the Standard Model   As a way to recall and honour Guido Altarelli I contribute to the discussion
on the prospect for the future of Particle Physics. I do this because I am sure
that Guido would have liked the discussion, even though I am not equally sure
that he would have agreed on all the opinions I express here.
