Maybe you should have read the article you linked:
The diamonds produced using this method are minuscule, hundreds of thousands of times smaller than those grown with the HPHT method. Hence, these diamonds are far too small for jewelry applications.
However, their use in technological applications, such as drilling or polishing, is a possibility. Due to the low pressure involved in the new method, it might be feasible to significantly scale up diamond synthesis.
Hol'up. Is that how you think scientific process, much less technological progress works? Truly? 👀
maybe it's a warning sign that you 2 don't have a close enough world view yet.
