This article sets Kant up for a failing. It compares Kant's spiritual description of the 'classes of creatures on Jupiter and Mars' and their behavior, with NASA's earnest scientific attempt to find extraterrestrial life. It's an apples to oranges comparison. The "balloon being filled" metaphor for collecting knowledge (data in this case), as a replacement for Kant's linear study across time, does not work with the author's intent. Studying and gaining knowledge is limited by the human lifetime, there's no two ways about it. For example; An army of sensors could collect all the data (filling the balloon) from extra-solar planets and an interpretation algorithm could crunch down exabytes of data into a human readable format. But in the end, a human has to read it and understand it. And the most the human could read and know, is limited by time. This article really does not plausibly discuss Kant.
