I doubt any of that is valid. Therac-25 happened 44 years ago, that's a very long time, and many people involved in cancer research today weren't even alive when it happened.

"Theryq" and "Therac" are not quite the same either. The word "therapy" and derivatives of it using "thera" are still used widely across the medical industry.

So I'm not really sure why anyone here is making a big deal about the name of the company being "Theryq".

It’s an s-tier case study for UX research though. Maybe the doctors don’t remember but we do.
