Your brain is now fully connected to a high speed wifi that you can toggle on/off, enabling you to browse the internet and the infinite amount of data it contains as much as you like.
Social media, Google, YouTube,,,etc you will be able to access everything in the online cyber space in your mind, and this connection can never be broken even if you are in different universes or dimensions.
Since this connection to the internet is an arbitrary link in your mind, it can never be traced, hacked, or tampered with in any detrimental way.
