OTOH, if you're willing to accept human-level error rates... why would you not do so at a burst-scalable task per minute and 1/1000th the cost?

I've built large human data entry operations. Variable throughput, monotony, hiring and perf management and firing, management, quality management. All of these things are large investments of human effort and money.

If I can achieve the same quality level (or in some use cases, even slightly degraded output) with software scaling characteristics and costs... I see zero reasons outside regulatory compliance reasons to have people do it.
