Tay was impressive but it was just a chat bot. For an AI to be similar to a human it would need to be capable of abstract concepts and reasoning, be able to adapt to any task it's presented with, draw from past experiences, combine separate disciplines, etc. AI can perform certain complex tasks, but those complex tasks are always within a limited context. AI doesn't have any comprehension of what an object is, and even if an AI 'trains' for countless instances they can be thrown off by simple changes like snow or film grain in a picture. AI is a long ways away from even mimicking human behavior outside of simple text based interactions, and mimicking is not the same as being equal to.
