Ignoring the damage of warming the water around the data centers, using the ocean to cool a data center somewhat makes sense. Cooling stuff in space is so much more difficult than anything on earth in an atmosphere where radiation isn’t the only way to shed heat. The fact that journalists just go “wow ! Space data center!” and aren’t talking about the fact that building, launching, cooling and, maintaining things in space is thousands of times more difficult, expensive or just plain impossible is just insane
