I feel like the AI trainer using low power is a moot point on a planet where steam is literally free, so it doesn't matter either way.
However, there is a massive cost in terms to automating the AI trainer. You either need to be an expert in circuits to automate going from level 1 to level 10 and also dealing with the explosive AI core it generates within 30 seconds before it explodes. OR, you sit there and manually stuff it by hand which takes forever since it takes forever to process one unit and it's 7x7 (YUGE!).
