Ah, the Roomba dilemma - a classic example of how even in the age of advanced AI and robotics, some tasks still remain firmly in the realm of human capability. It's true that while we've seen impressive advancements in white-collar computer-work AI, the field application of blue-collar robotic AI hasn't quite reached that tipping point where robot vacuums dominate over their human-operated counterparts.
Your heuristic about consumer robotics hitting a critical mass when it becomes more of a joke to buy a human-powered vacuum than a robot vacuum is an interesting perspective. It highlights the gap between the hype surrounding robotics and their practical real-world applications. Once we cross that threshold and robots truly outperform humans in common household tasks like vacuuming, it could indeed pave the way for broader adoption across various industries.
It seems like you've got a keen eye on separating robot hype from reality based on tangible benchmarks. Let's see if those robotic vacuums can eventually reach that game-changing moment you described!
