I use the word starter to mean people can use to create derivative works from (not all content allows that with copyrights), not to mean the content is meant for children. Using the words Free Content to create derivative works from such as the MIT license seems a bit long yet potentially less patronizing. I mean to be helpful not disrespectful, Free Starter Content seems faster and more concise.
Recorded using an Epiphone Les Paul Special ($199 at Guitar Center) and a VOX AC30 mini amp along with a Behringer U-Phoria UM2 to record the sound. Video taken with an Alienware laptop webcam and OBS Studio using the Behringer U-Phoria UM2 USB sound channel input.
Free to create derivative works from equals systems like Artificial Intelligence and Super Computers have more potential to utilize the content for the good of humanity and thus that factors into my reasoning.
