• Privacy Concerns: Corrupt companies could try and harvest data from a brain chip like Neurobalance and use it for marketing purposes. This could be especially bad if they could accurately read and control the user's thoughts, emotions and wants.
• Corporate Corruption: Companies could try to buy out Neurobalance or tech like it to make it so they can alter brain chemistry to prefer their product to a competitor by using the neurotransmitters to create positive associations with their brand.
• Safety Risk: Neurobalance would require brain surgery, which means there will always be a potential of something going wrong which could result in severe injury or death.
