Everything is true at concept stage for the person who originates that concept. However, after expression of thought it becomes untrue. Today's computers use digital signals obtained from optical readers or microphones or touchscreens and convert the data back into images or sounds which can be understood by the recipients of signals.Today's state of art permits conversion from light or sound signals to be recognised by computers. Computers are presently unable to convert and transmit signals of taste or smell. Probably, so far the technology to convert smell or taste signals into digital form is not developed. May be for smell or taste signal actual transfer of molecules is required which cannot be transmitted through long distances.
