  First of all, an importance of the LHC and FCC based energy frontier
lepton-hadron and photon-hadron colliders is emphasised. Then arguments
favoring existence of new heavy isosinglet down-type quarks and vector-like
isosinglet or isodoublet leptons are presented, following by historical
arguments favoring new (preonic) level of matter. The importance of Super-Charm
factory and GeV energy proton linac for Turkey national road map is argued.
Finally, several recommendations for ESPP2020 are suggested.
