Sure, but very few regular people have patience even doing D&D websites. Imagine though that you just take your phone, tell it "make a website", then look at it and say, "well, change background to this photo", "hmm, place a gallery from a wedding there", "make a new page linked on the left and call it 'about me'" etc. And you see the changes happening immediately after you say it, and you can even correct it. This is doable today, you just need to have a set of "code blocks" that would allow you to generate proper web app and via engines like phonegap even mobile apps anyone can make. Imagine you run a small business and need just some simple site with your contacts, and you are able to assemble it with voice in 10 minutes. That would be a complete game changer for most regular people.
