Not the author, but really nice that they shared some real data points:

> Once our Text-to-SQL solution was in production, we were also able to observe how users interacted with the system. As our implementation improved and as users became more familiar with the feature, our first-shot acceptance rate for the generated SQL increased from 20% to above 40%. In practice, most queries that are generated require multiple iterations of human or AI generation before being finalized. In order to determine how Text-to-SQL affected data user productivity, the most reliable method would have been to experiment. Using such a method, previous research has found that AI assistance improved task completion speed by over 50%. In our real world data (which importantly does not control for differences in tasks), we find a 35% improvement in task completion speed for writing SQL queries using AI assistance.
