Since the story came out people fixated on "lol he used a shitty gaming controller" but really that is one of the least sketchy design choices in the entire rig. Why reinvent the wheel and make a custom set of controls that are realistically another huge expense and potential failure point, when off the shelf solutions exist for that component?

The corners that were cut are the ones involving the viewport/nose adhesion to the ships frame, and the structural integrity of the carbon fiber hull itself. They had test data suggesting it was a bad idea to engage in repeated dives with their design, and an even worse idea to operate at the depths they chose. They decided to ignore that.

Using commercial off the shelf technology without proper testing and certification is absolutely cutting corners. See: Kaprun disaster.

What kind of fire rating did those COTS parts throughout the interior of the vessel have? What kind of redundancy existed? Would you use a Logitech controller for a spacecraft? The requirements of deep sea submersibles and spacecraft are quite similar. Would any of the submersible certification agencies approved this? I think not.

I see the Logitech controller, the carbon fiber hull, and so many other decisions he made as symptoms of the same corner cutting, “move fast and break things” mentality he had.

Exactly this. When you procure custom hardware, you’re paying (a lot) for the vendor to ensure that each unit meets the specifications you provide. If you validate off the shelf hardware like this, there is no guarantee that another batch of the same sku will also meet your requirements. Imagine training on these controllers then a certain batch of them has wildly different sensitivity.
