  We start this short note by remembering the beginnings of the Warsaw School
of Quantum Optics, evidently stimulated by Iwo Bialynicki-Birula at the Warsaw
University, and then Centre for Theoretical Physics of Polish Academy of
Sciences, and Adam Kujawski and Zofia Bialynicka-Birula at the Institute of
Physics of Polish Academy of Sciences. In the theoretical approaches of the
Warsaw School Quantum Field Theory was always present, and Quantum Optics was
considered to be Applied Quantum Electrodynamics (QED). All of us who grew up
in this fantastic community have carried and are still carrying the gospel to
others. In particular, now QED began her run on the red carpet of Super
Instense Laser Matter Interactions, Attosecond-physics, and Ultrafast Laser
Physics, in general. We will elaborate on the recent progress in this
direction, and on the open questions towards future investigations. This paper
celebrates the 90th birthday of Prof. Iwo Bialynicki-Birula, our QED guru!
