"These were too common. It's supposed to be dangerous, difficult, and expensive."
The idea here is similar to DCD. After enough rips, your brain slowly starts to have trouble comprehending what's SIC and what's internal dialogue, as the neural tissue is damaged over time. Each time you're ripped (with increasing chances from failures and crit failures), there's a cumulative chance to develop a neurological disorder that prevents you from discerning between SIC, internal dialogue, and your own speech centers.
The way this would manifest with overwritten attempts at speech the way that being drunk does. Someone trying to coordinate over the phone for a hit, suddenly shouting about ROBOT ONLY WANTS TOOTHBRUSH, Akalumpa gunna getcha, and other classics?
The remedy here would be time and expensive treatments, with severity increasing the more rips you have performed without medical assistance.
My main concern with an idea like this would be impeding RP, rather than attributing to it, and also people just repeating what they said before until it was understood.
However, I think having something similar would add flavor to rips, the maddening nature of SIC, and create some hilariously unfortunate incidents.
