Brain computer interfaces (BCI) are already here in the form of external (non-invasive) and internal (invasive) systems. Putting aside the risks from invasive surgery, do you want your data ‘out there’?…:

Finding out that your information has been accessed by a data breach is never pleasant, but that someone could have been browsing your thoughts patterns or emotional states? It doesn’t bear thinking about.
