Ask HN: Real examples of quantity leading to quality (not the pottery parable)

I keep seeing the pottery class parable being used as an example of how quantity leads to quality.

Is there other better real life examples?

I found a few like Jennifer DeWalts 180 websites etc that I detail here (https://joshdance.medium.com/pottery-class-parable-or-real-examples-of-quantity-leading-to-quality-934760ebbcf3) but I would love to find other examples.
