In field of creativity, I think that a new technology never really make previous techniques obsolete.
We tend to continue to use ways of working that are not recognized as efficient, just to feel what is expressed by serendipity of erratic imperfections.
There are still people making stop motion animations or pinscreen animations.
Generally, I think that disdain is the case for some artists. But in my opinion, for most of them, that is more a lack of interest.
But , here, I don’t think that critique of 3D scanning technology corresponds to that.
A 3D Scan may be generated from various ways. And they have their downsides.
If you read a comment about the fact a laser scanning may be precised but may correspond to a huge amount of geometry data to deal with and at same time no coloring data.
If you read about photogrammetry that may offer color but may also result in a crappy geometry.
That could be totally legitimate critiques made, some years ago.
And relatively to situation, if you try to make 3D Scanning with a poor equipment and poor data as inputs, they still may be valid.
If you only have an old computer, not the latest pro camera and not the best software of photogrammetry ; that may feel less painful to sculpt from a photograph than to take and treat hundreds of photographs during double amount of time.
Same thing happens with motion capture, amount of time necessary to clean-up irregularities in capture may be represent an insane amount of work.
What makes mocap more related to expressed feeling is that can be incredibly boring for animator.
That is a lot less interesting than being the guy in charge of performance.
When there is no mocap ; the animator is the only interpret, responsible of character expression.
When your job is just to clean imperfections that computer is not able to understand ; I think you may have the right not to be enthusiast.
Now, after some training, AI should eradicate those jobs.
I don’t think people will be sad that nobody will call them to do uninteresting work.
I don’t think that majority of people are complaining to scientists that they should not give repetitive tasks to robots.
People’s lives may be affected to have less jobs.
But that is a problem related to stupidity of economics laws.
They don’t recognize that human’s knowledge, rarely expressed, is precious and that you can’t reprogram a human as fast as a machine.
