  Dedicated to the memory of Prof. Veltman, one of the founding fathers of our
discipline: his legacy lives on. Many times we have to turn back and follow his
footprints to find the right path. After reviewing general aspects of high
energy physics where he gave a seminal contribution we will introduce recent
developments in the standard model effective field theory, showing how the
whole movement from renormalization to predictions plays from Veltman to SMEFT.
