Predictions of AGI Takeoff Speed vs. Years Worked in Commercial Software

This page features a rough depiction of different views on the question of whether artificial general intelligence (AGI) will take off in a "hard" way (fast, no time for response or competition) or a "slow" way (more gradual, more time to integrate with society, possibility of competing projects). I plot these views against a very crude estimate of how long each forecaster has worked on commercial software (not counting academic computer science). It would be interesting to slice these predictions along many other dimensions as well. It would furthermore be helpful to gather statistically valid data from surveys of AI experts. My graph here is just something I put together in a few hours based on what I already knew offhand.
