Yes, in areas like testing discipline. I don't accept the argument that you can skip past the fundamentals and it'll all just work out because you may be able to help some people quicker. That's everyone's goal in that space - to get implants onto the market as fast as possible.
If anything, being sloppy is a point against you when you’re working in particularly impactful stuff, because it shows your skills as a scientist aren’t up to the standards of the field you’re researching.
It's not just that the research could be done with less suffering/death, it's also that this is also not really the highest-priority research if we want to improve the lives of differently-abled and disabled people. But we're being asked to excuse bad research practices that result in unnecessary death because somehow Neuralink specifically is an emergency that needs to have market domination as soon as possible to save lives.
I have no objection to Neuralink responsibly conducting research in this direction, but it's far from the most effective or optimistic way that we could be spending that time and money, so I don't see why they specifically should get a pass to violate research ethics. They're already devoting resources in a way that is sub-optimal if you just want to improve the lives of disabled people as quickly as possible. And that's fine, but at least they can devote those resources responsibly without causing additional suffering.
