Even accepting for additional cost with human. With the current model we are still roughly 10^3 in terms cost.
Less risky to deploy question will probably come once it is closer to 10x the cost. Considering the model was even specifically tuned for the test and doesn't involve other complexity I will say we are actually 10^4 cost off in terms of real world scenario.
I would imagine with better algorithm, tuning and data we could knock off 10^2 from the equation. That would still leave us with 10^2 cost to improve from Hardware. Minimum of 10 years.
