What are the challenges and limitations that mind-reading technology needs to overcome for true telepathy to be achieved?

For true telepathy to be achieved, the decoding technology would need to significantly increase in accuracy and resolution. It would also need to understand tone, emotion, and contextual nuances of thoughts. Additionally, the system would need to work in both directions, allowing for the sending and receiving of thoughts between individuals.
