Btw, what you are really asking is a better input interface for content creation. This doesn't need to be "integrated" into our biology. A proper UI that would take speech commands (so that you don't have to write) and directions (where to place photos, what stuff to highlight, put to the center, etc etc) is probably 3-5-10 years away and will not be invasive.
Speech doesn't work when it is noisy or privacy is required. A similarly non-invasive interface is a hand holdable, or wearable chordic input device, like the one in the Hip PC:

Noise is a problem now because the proper filtering algorithms don't work so well, but good AI will do it. Privacy though, that's a problem so in those cases it may require inventions like yours or miniaturized non-invasive neural readers in something like a headphone set.
Speed of speech is actually slower than the speed of thoughts. I read in speed read guide somewhere that one should reading out words in your head as it actually impede the speed at which the words are processed.
Have you ever had a time when a name or word is that the tip of your mouth but you can't get it out? That's the link between thought and speech malfunctioning! With the right set up, a machine can theoretically know what you mean better than yourself!
at least 1000 times slower, at times...
