Dangerous! Two to four years without his most competent enployees and other mech designers and mech pilots? I’m assuming he’ll upgrade his best. This is dangerous!

Not bad, especially when you keep in mind this is just from the Polymath. As she said, his development is too important for them, so they'll go all in in assisting with the transition. Plus, I don't see the Eden Institute and Divine Mox remaining idle and letting them be the only contributors to his growth, since it's the perfect time to invest in what will almost certain yield great returns.
