I thought the title was "Ariel" but I can't find anything searching on Google. The story was about a guy who owned a large computer company trying to build an AI computer. He is widowed and his son plays games with the new computer in secret. The game playing leads to the machine becoming self-aware. The father finds out about the boy's games. Some bad guys show up and burn down the building with the newly aware computer, killing it. But it turns out the boy kept copies of the game sessions on disk, so the AI can be revived.
Does anyone remember this story?
