Exactly. Costs for computing/disk storage go down exponentially. Cryptocurrency tx/sec goes up exponentially. As long as the two rates roughly cancel out, we're okay. If they're massively different rates, then you're still dealing with an exponential which is difficult. Either way though, lightning is a linear benefit, not an exponential one.
