Exactly, it would actually benefit many C/C++ programmers. Some components of NT are very high quality, why not wash their license if the aim is to empower the programmers and also make some profit?

Because then your Re4ct code would look like this:

    export default class USERCOMPONENT extends REACTCOMPONENT<IUSER, {}> {
    constructor (oProps: IUSER){
      super(oProps);
    }
    render() {
      return (  
        <div>
          <h1>User Component</h1>
            Hello, <b>{This.oProps.sName}</b>
            <br/>
            You are <b>{This.oProps.dwAge} years old</b>
            <br/>
            You live at: <b>{This.oProps.sAddress}</b>
            <br/>
            You were born: <b>{This.oProps.oDoB.ToDateString()}</b>
        </div>
        );
      }
    }

Easy pal, we don't want to multiply that shyte.

> And why not train it on microsoft windows and office code?

As a thought experiment, if one were to train a model on purely leaked and/or stolen source code, would the use of model step effectively "launder" the code and make later partial reuse legit?

Only if it's not microsoft's leaked code, I guess :)

That is a rather good question.
