It depends on the concept. ivanbakel is not making some blanket claim that things always require complex technical terms. He is just saying that language -- including field-specific jargon -- evolves so that people steeped in the language can explain things to each other. The clearest example of that how hard it is to decypher popular articles about quantum mechanics. Here, even when explaining concepts at a skin deep level, stories they tell are utterly inadequate if not misleading. That's because even the basic concepts of QM are ones from linear algebra. And is shy Feynman was a sometimes devotee of the "shut up and calculate" school of interpretation.
