DESCRIPTION:I will present evidence in core-collapse supernova remnants fo
 r the action of jets in the supernova explosion process. Two main types of
  observations appear in many\, but not all\, core-collapse supernova remna
 nts: (i) the well-established presence of a pair of opposite `ears’ and 
 (ii) the recently identified point-symmetrical structure in 15 remnants\, 
 including SN 1987A\, Cassiopeia A\, Vela\, and the Crab Nebula. The pair o
 f opposite ears suggests that two opposite jets inflate the ears. The poin
 t-symmetrical structure results from two or more pairs of jets along diffe
 rent axes\, as the jittering jets explosion mechanism (JJEM) predicts. I w
 ill compare the JJEM with the neutrino-driven mechanism and conclude that 
 the neutrino-driven mechanism comes short in explaining observations\, lea
 ving the JJEM as the primary explosion mechanism of CCSNe. The JJEM has so
 me unique signatures in addition to its point-symmetric morphology\, such 
 as gravitational waves and energetic explosions. I will comment on the ove
 rrated popularity of the neutrino-driven mechanism in scientific meetings 
 and literature.
