Everything can (and will) be weaponized, so the only realistic way to approach it is as a cost/benefit analysis. If something can bring more good than harm, excellent. If something can bring more harm than good, then maybe rethink things.
The upside to this technology is allowing a few people to communicate who have neurological damage. The downside is every government on earth being able to read your mind. Sounds like a good trade!
To not work on anything where the risks from its potential weaponization outweigh the likely benefits of beneficial uses?
anything can be weaponized, john wick kills people with a pencil :)
John Wick is a fictional character, we should use real examples when discussing the real world.
Computers themselves are a pretty decent example, I think.
