never say that it can't happen, because the possibility is definitively there.
Even although they are still not usable for making good 3d models, computer programs that involve neural networks are already being invented with the ability to make up the "missing information" you mentioned.
Basically, such a program first runs recognition software to know what the image is about, then it uses internet to find thousands of pictures of the topic, then it filters out relevent images of the right angles.
Then using the information from hundreds of selected photo's, it could compose a 3d model without it missing out on any information.
As far as i know, there are no programs like this for 3d objects "yet" but i have seen some very impressive results when it comes to 2d images/photo's that have been produced by a computer from just a text entry alone.
When the first good version for 3d models will be developed? i don't know, might be 10 years, might be a 100. But the possibility of it being developed is very real.
