It isnt all technology, I mean almost everything is technology. Making swords, building cabins, even cooking food uses some kind of technology. It is only certain types of technology. For example, cell phones transmit demigod voices over the air waves and monsters can somehow use that to find demigods. Piper also uses a laptop to talk to her dad, but Chiron says not to take to long as it is dangerous. It is also said at one point a demigod googled gorgon and they appeared, but that might be more of a "saying their name gives them power" kind of deal as Percy and Annabeth freak out when Rachel shoots to a group of people that they are demigods. So anyway, basically just technology that can transmit their voices
