That&amp;#x27;s unlike chess or go where the interface isn&amp;#x27;t important. The really impressive feat will be an AI that uses the same sensory information to make decisions (and I really hope that&amp;#x27;s where the openai will head next)</text></item></parent_chain><comment><author>BaronSamedi</author><text>I completely disagree. An API is software&amp;#x27;s natural input mechanism just like the senses are a human&amp;#x27;s natural input mechanism. Having the AI use human senses unfairly handicaps it. More importantly, however, is that this is not the key problem.&lt;p&gt;The key problem is teaching the AI strategy and tactics. What heroes to pick? Where to lane them? When to rotate? What items to buy? What spells to level up? What enemies to target with which spells and in which order? These are the hard problems and they are very hard indeed. A 5v5 AI will have to become expert at risk calculation, Pareto optimization, basic military principles, and many more things. Compared to these problems, the choice of input mechanism is trivial.</text></comment>

Having an AI plan and learn strategies to play a game. This is a separate problem from machine vision, which is being worked on by tons of other people. Adding a machine vision requirement wouldn&amp;#x27;t help them with their goal and would take 100x more computing resources.&lt;p&gt;OpenAI could probably afford to do it, but it no smaller researchers or hobbyists would be able to compete.</text></comment>
