This question is a duplicate of this one with a stronger operationalization for artificial general intelligence, and including robotic capabilities. I will copy relevant parts of that question to this one.
Since the inception of the field, the goal of Artificial Intelligence (AI) research has been to develop a machine-based system that can perform the same general-purpose reasoning and problem-solving tasks humans can. While computers have surpassed humans in many information-processing abilities, this "general" intelligence has remained elusive.
AI, and particularly machine learning (ML), is advancing rapidly, with previously human-specific tasks such as image and speech recognition, translation and even driving, now being successfully tackled by narrow AI systems.
But there is a stunning diversity of opinion about when general AI may arrive, according to published expert surveys. For example this study finds 50% of AI researchers accord a 50% probability to "High level machine intelligence" (HLMI) by 2040, while 20% say that 50% probability will not be reached until 2100 or later. Similarly, this survey finds an aggregated probability distribution with a 25%-75% confidence interval (comparable to Metaculus sliders below) ranging from 2040 to well past 2100.
It would be nice to tighten these probability intervals considerably, so we ask of the Metaculus community:
