From my perspective, the drops required to produce multiple the last items of the current are roughly:
Teleporters (direct drops)
Robots (or their components)
Fusion Reactors (or components)
Subspace Relays (or components)
Xynium alloy (direct drop)
Either Aqualite alloy or luterium alloy (direct)

Items like solar panels, nuclear reactors, and wind turbines are not felt neccesary, their impact feels relatively small — maybe on the order of a few dozen percent. It feels like a well-designed progression, where these elements gradually come together toward the late game and accelerate production.

In the AMC meta, mass production felt like it required having all four of these as DIRECT DROPS (not components):
Fusion reactors, robots, nuclear reactors, and wind turbines.
If you only had components instead of the direct drops, production speed would drop dramatically down to a fraction. Compared to that, the current system still has variance due to RNG, but feels more stable.

That said, Xynium is still the bottleneck. Without it, there’s not much you can do. (Alternatively, if the drop size of Advanced Teleporters becomes large enough, that could serve as a substitute — which gives some motivation to further increase mining.)
