Is DeepMind's Gato AI really a human-level intelligence breakthrough?

DeepMind's Gato may or may not be a major breakthrough for AI DeepMind has released what it calls a "generalist" AI called Gato, which can play Atari games, accurately caption images, chat naturally with a human and stack coloured blocks with a robot arm, among 600 other tasks. But is Gato truly intelligent – having artificial general intelligence – or is it just an AI model with a few extra tricks up its sleeve? What is artificial general intelligence (AGI)? Outside science fiction, AI is limited to niche tasks. It has seen plenty of success recently in solving a huge range of problems, from writing software to protein folding and even creating beer recipes, but individual AI models have limited, specific abilities.
