I’m not sure what you mean when you say we don’t need real people to build 3D models. If we want 3D models, someone has to make them. That person might be a traditional modeler working in Blender, or a sculptor in ZBrush, or might be someone with a 3D scanner doing photogrammetry. The tools are changing, but it is still people using the tools. Just like how we invented an “automatic programming” system where the comp…
They're comparing making a bespoke 3D model of a character as opposed to scanning an actual person, saying similarly you could just create a voice from scratch rather than record a real one.
A 3D scanner is an artist’s tool. By using a 3D scanner, you aren’t getting rid of artists, you are just changing how artists do their jobs. Vocal synthesizers and vocal transformers, similarly, aren’t making it possible to press a button and get reasonable sounding voice in your games if you don’t have a voice actor making it possible. If you aren’t convinced, then just look at soundtracks. You can press a button and your iMac will spit out the sounds of the BBC Symphony Orchestra violin section. In spite of this, getting a symphonic score is still expensive. It’s expensive enough that TV shows (with sizable budgets) often skip out on the symphonic score and do something cheaper. We haven’t gotten rid of musicians, it’s just that musicians are much more likely to have computers.
There is, in theory, nothing stopping you from buying like $200 in software and making a symphony orchestra right now. The problem is that you have no idea how to write a symphony orchestra. For the same reason, if you have an iPhone 12 or something similar then you can start using the LIDAR features and making a 3D model using photogrammetry in moments—except for the fact that you have no idea how to make a 3D model.
I think there’s a trap that people fall into, thinking that technology is just around the corner that will get rid of job X, Y, or Z. Often what you end up with is MORE people doing job X, Y, and Z, it’s just that they use computers to do it, and have a different skill set.
