TESOL2 is achievable using a brain-computer interface (BCI), sometimes called a direct neural interface or a brain-machine interface, and is a direct communication pathway between the brain and an external device. BCI implants in humans now exist, designed to restore damaged hearing, sight, and movement. The similarity throughout the research is the remarkable cortical plasticity of the brain, which often adapts to BCIs, treating prostheses controlled by implants as natural limbs. With current and future advances in technology, scientist can now produce BCIs that translate speech for second language communication, acquisition, or treatment of disease where an individual requires the regeneration of speech.

A possible development in the evolution of communication is the replacement of language with images. This development enables larger chunks of information to be transferred between individuals in less time than traditional language. Using machines such as a brain-computer interface, it is possible to capture and transfer brain images, from human to human, and human to computer. This technology enables machines to provide calculations and solutions based on imagery.

Man-computer symbiosis is an expected development in cooperative interaction between men and electronic computers. It will involve very close coupling between the human and the electronic members of the partnership.

TESOL2 is a transition into virtual worlds achieved by machines interacting directly with the brain's visual cortex; allowing images to transfer from human to human, and computer to human, enabling an unencumbered experience in virtual worlds.
