It is a meme that references Plato’s Allegory of the Cave. In Plato’s allegory, people are chained up in a cave from birth, only able to see shadows projected on the wall by a fire. They believe these shadows to be reality. One person escapes the cave and goes up into the real world, where they see the sun and other things. The text in the meme says “Old PC Under a Desk” which represent the shadows on the wall that the prisoners in the cave mistake for reality. The text “EC2 Instances, Serverless, Kubernetes” refers to cloud computing concepts, which are likely the “real world” that the person who escaped the cave discovered. So, the meme is suggesting that some computer science concepts might seem strange and unreal to those who are not familiar with them
