“Time it takes for a human to complete a task that AI can complete 50% of the time” seems like a really contrived metric. Suppose it takes 30 minutes to write code to scrape a page and also 30 minutes to identify a bug in a SQL query, an AI’s ability to solve the former has virtually no bearing on its ability to solve the latter but we’re considering them all in the same set of “30 minute problems.” Where do they get the data for task durations anyway?
