They’ll happen. I’ll be dead but idc – It’s like computer paint. I have the plans and know what materials will work to make it happen but our technology has at least 80-120 years to go for it to happen. Basically, paint with embedded self-organizing computer ‘stuff’, including display, ccharged by whatever is around [people stepping on it if it’s the sidewalk, air… sound… and the display is human touch sensitive. and connected to everything. That way our computers are painted on every surface. Easy. But, we’re not there yet.
