So, while this was not a path available for the forces of Middle-Earth, it has been stated clearly that it is possible for a smith of greater skill than Sauron himself to dismantle the One Ring. At that point, that included only Aule himself, and maybe Saruman, and Saruman had gone off the rails by this point. Obviously, there exists no smith in all of the modern world able to match Sauron's skill either.
However: This is skill. Or perhaps a combination of skill and talent. Skill can be developed. Skill can be engineered. At least some forms of modern industrial forging can quite rightly still be considered 'smithing' -- we just designed bigger hammers, anvils, and tongs, for bigger, more precise hands.
The scenario is as follows.
The One Ring appears in modern day Earth. It is already telepathically isolated and blocked from luring people.
All of humanity is immediately "Dismantle-the-One-Ring"-lusted. That is, all humanity is united in the common goal of developing - by any means necessary - a smith who can exceed Sauron's skill and dismantle the One Ring. Bioengineering, software development, hand coded programs in assembly, generative neural network growth, immortality research, bio-networking / consciousness unification, and other things are all valid possible paths, though unfortunately I suspect the one that will be most obvious in today's climate is generative AI.
The 'smith' does not have to be human, or even necessarily sapient. It doesn't have to be good at anything besides smithing work. It does have to have a sufficient understanding of smithing to be able to outperform Sauron at this particular task, which is far more than an unmodified human is capable of, and it does have to be a single individual rather than a team (although things like gestalt consciousnesses can quality).
How long does it take for humanity to engineer someone or something that can dismantle the Ring?
