Spain-based designer Fernando Barbella has a Tumblr blog, in which he imagines the types of signs we can expect to see in the near future.
Called ‘Signs From The Near Future’, the blog features dark photos of signs containing warning messages like ‘Drones watching’ and ‘Keep left lane free for driverless cars’.
It hints at the possibility of technology being so advanced that more machines are going to replace activities currently fulfilled by humans.
Check out the rest of the signs below:
