Exactly. I don't know why I've been hearing this so much lately. I've been researching about learning to use 3D software (3dsmax) and I get the same responses that I hear about learning to code: "oh it is very difficult and it will takes at least 5-10 years to be able to build anything of quality" Personally, I think if it takes you 10 years to become decent at anything, then you are doing it wrong.
I don't know. I think some things can legitimately take some people ten years to learn, even if they are doing it right. However, my disagreement is that sometimes learning something at a cursory level, even if it doesn't allow you to do quality work, can be worthwhile. It can give you insight and appreciation of the discipline and help you work more effectively with the people that really do it. It can also be fun and make people feel proud to just be able to do it a little.
Just a quick datapoint. I've used 3dsmax casually (free, academic version), and I managed to produce some images of which I was quite proud. They weren't magnificently detailed scenes, but they were photorealistic representations of the objects I was modeling. So no, it definitely doesn't take 10 years to get to the point where you can make something meaningful in 3dsmax.
It does, however, take grit, because there's a ton of documentation to read, particularly concerning rendering settings.
