Yes, it is about ideas not words. You can learn the word, it does not forcibly tell you about the ideas. Especially the new one.

If a software has been done, buy it! It will be almost always less expensive than building it. If it has not been done yet, no book or knowledge can tell you how to do it.

And if an idea you can code is new, you'll hardly have the word for it. It is easier to brag about «well (re)known ideas» than doing new stuff.

Colours you can't see are ideas we have not yet the word to describe them to those who can't see them.
