Do you think, one day the technology will be developed by which each and every single human being can be monitored continuously without any device with them; just sensing their DNA barcode? Their location, activities, temperature, wellbeing, etc.
That wont be a very good thing Sir, if that at all happens. I dont think scientists should brainstorm in that direction. But rather it would be great to have a device which when touched into any organism or plant can identify the exact species, without performing the lengthy protocol.
