I don't understand the problem the article mentions. It says we can't produce terahertz waves while showing an infographic showing that visible light are terahe

  It does not say that we can't produce terahertz. It says that there are no consumer products that make use of terahertz, because (among other reasons) producing it is more challenging than, say, producing microwaves. That statement is correct. When people say "terahertz radiation", they do NOT mean visible light. They are referring to radiation between (roughly) 0.1-10 THz, which is much lower frequency than visible light.

    Well then the article is terrible at communicating science. I had the same confusion arise as many others in this thread and it looks like in order to understand the article you already needed to have understood all the jargon and what the problem is a priori.
