             | You are confused because you interpret the meticulous and
             | time-intensive nature of the research as potentially
             | conflicting with the claims of affordability and ease of
             | application. To clear up this confusion, let's break down
             | the key points:
             | 
             | 1. Affordability and Ease of Application: The article
             | states that the radioisotopes are intended to be an
             | affordable and easily applicable method for marking rhino
             | horns. This means that the technology, once developed and
             | refined, can be applied to rhinos without significant cost
             | or complexity. The goal is to make it practical for
             | widespread use.
             | 
             | 2. Three Years of Research and Expert Collaboration: The
             | three years of research and the involvement of a team of
             | experts highlight the rigorous development and testing
             | phase needed to ensure the method's safety and
             | effectiveness. This initial investment of time and
             | expertise is necessary to create a robust, scientifically
             | validated solution.
             | 
             | 3. No Contradiction: The extensive research and expert
             | collaboration do not contradict the claims of affordability
             | and ease of application. Rather, they ensure that the final
             | product is safe, effective, and ready for widespread,
             | practical use. The upfront investment in research is
             | typical for developing innovative technologies and does not
             | imply that the method itself will be costly or complex to
             | implement once it is ready.
             | 
             | 4. Scaling Up: The project's next phase involves closely
             | monitoring the rhinos to demonstrate the method's efficacy
             | and safety. If successful, this proof of concept will pave
             | the way for scaling up the application to more rhinos and
             | potentially other endangered species. The affordability and
             | ease of application refer to the potential widespread
             | deployment after the initial research phase, not the
             | development phase.
             | 
             | In summary, your confusion arises from conflating the
             | initial research and development effort with the final
             | application's intended affordability and practicality. The
             | article suggests that after this rigorous development
             | phase, the method will be straightforward and cost-
             | effective to implement on a larger scale.

             | I'm not quite convinced of this. If you watch the video in

             | that they typically paint the rhino's horns with substances
             | to make them undesirable to poachers, they clearly have the
             | capacity to subdue and restrain the rhino already. And in
             | the video they show a person using a standard hand drill,
             | who drills into the rhino. You can see this at 0:20 and
             | them insert the device at 0:34, where just after they show
             | another horn being drilled into. And they do it several
             | times throughout the video while the narrator explains the
             | process.
             | 
             | I suspect that the 3 years is far less due to the actual
             | "installing" it into the rhino (as it looks like once
             | subdued the process is really <15 minutes...) but rather to
             | things like regulation and determining the nuances like
             | "how many isotopes do we need" (clearly more than one),
             | "what types of radiation are more detectable?" "what levels
             | of radiation will sustain and be detectable when
             | transporting horns across international airports?", "Are we

             | the radiation leech into the rhino's body, such that while
             | the device is safe inside the horn it would be harmful,"
             | "how often does that happen, especially given when they
             | fight?", "do the devices stay in place for sustained
             | periods of time?" and so on. There's quite a lot of
             | important questions and many I'm sure that an actual expert
             | in this could ask, but I'm nowhere near a rhino expert (or

             | technologies] and I have a bunch of questions that would
             | reasonably take years to adequately answer.
             | 
             | It isn't "ah fuck, rhinos are so hard to catch that we're

             | years later?" and "oh fuck, that type of glue and that
             | drilling depth didn't work because we lost 10 devices in
             | the first year. Time to update our methodology."
             | 
             | I find these kinds of questions magnitudes more likely than
             | the explanation that they couldn't catch 20 rhinos and
