A little pedantic: you already have thousands of different input sources, from the classic "five senses" to less conscious awareness of things like your limb placement and internal biochemistry (e.g., hunger). There are even people who've "added" artificial senses by doing things like placing magnets under their skin (to sense magnetic fields) or strapping a device to their leg that buzzes in the direction of North. Not to mention the fact that we can use things like visually inspecting a screen to access senses (via information feeds) that are not available biologically. However, you're right that a robot/AI developed with the intention of feeding it all sorts of heterogeneous data will probably be able to process everything more effectively. In my own research (AI with a focus on reinforcement learning and robotics) I am sometimes surprised by how effective agents can be at making sense of their input streams. For example, an experiment will not go the way you expect because the robot can trivially solve a maze via sensing the current in the wiring beneath the floor. Of course, there's a limit in terms of how effective raw information can be. Humans don't need to see ultraviolet wavelengths because in general the spectrum of ~350-700nm provides all the information we need, and the brain is good at finding the salient aspects of what we see. If you just connect a new sensor to a robot, it might improve its ability to understand the world, or do nothing at all, because it can't incorporate this new information into its representation effectively. Or it doesn't add anything new, or at least nothing that it couldn't have figured out from existing input streams. For example, adding a stock ticker feed to your robot would probably not help it solve a particular task, unless your robot happens to be 50 feet tall and the task in question is "rampaging down Wall Street".
