Defold.

Floorp. It's open source fork of Firefox made by mostly Japanese developers. It's noticably faster, privacy focused than the original and have more customisation options.

I'm surprised it's not well known to be honest.

I think two assumptions to this whole 10k people/day metric cause it to be inaccurate pseudoscience:

1. It assumes people learn things at random times, causing the distribution to average over 30 years.

2. It assumes everyone learns a thing by age 30. If you talk to anyone over 80 years old I guarantee they'll tell you they don't know everything.

It's a sweet sentiment, but it bugs me how people keep quoting this like there's any truth behind it.
