Moore's law is a (awesome) example of what economists call "learning curve" specifically for transistors. Generally, economists model unit cost as Y and cumulative unit volume as X.

The industrial revolution was all about learning curves. Production grew, got better, leading to lower prices, leading to more demand, more production, more learning, lower prices, more demand... untill everyone had as many forks, socks and radios as they wanted.

But... Moore's law is usually represented as price over time instead of units. Half the unit cost every 18 months.

Early-ish in the tesla days elon went on a sort of rant. I think underlying it is/was this difference between "x as unit volume" or "x as time." "Time" made technologists think of learning curves in semi-supernatural terms. They either exist or they don't.

Moore's law was so consistent for so long, we just viewed it as a constant, but traditional economists would say it was/is a function of all the computers that got produced. Elon would say it's a function of hard work at intel, etc.

The upshot is the same though. As more batteries are made, more people work on battery manufacturing methods & R&D, the price declines.

There's no guarantee that it'll be proportional to volume but... new energy tech (batteries, solar, EVs) is now crossing price-parity thresholds in all sorts of applications (like grid power). That means more demand, more learning, lower prices, more demand.

TLDR: yes, propbably
