"[F]or example, in the case of many of OceanGate’s innovations, such as carbon fiber pressure vessels" This ain't the innovative win they thought it was. In fact, it's a self-own. I recently saw a material scientist that specializes in carbon say there wasn't enough money in the world to get her to ride inside a carbon fiber submarine. Why? Carbon fiber has a very high tensile (i.e. stretching) strength. However, it's quite weak when under compression. Guess which strength is important when operating in a high pressure environment? Submarines, including deep submersibles, are kind of a solved problem. That doesn't mean there aren't risks involved, but when was the last time a submarine imploded above it's intended operating depth? The 1950s?
