How to do it
It's obvious that this technology will introduce inequalities. But it's just like internet access, now most people take it for granted even though it was a privilege at some point, became a 'norm' in developed countries, and is now (or should) be available for all : we can't afford a global and uniform access to it.
The same is true for simply accessing a computer.
We need to make sure that those who access this technology first are those capable of making it more popular. It must first be a tool for scientists and innovators. It will allow for a faster and wider spread sooner.
As for the privacy concerns, make it sure that no data can get out without a 'mind decision'. Create a mind firewall first.
