What a top class comment, solarguy. You're totally right about China's technological advances given mass production output and the economies of scale we have been enjoying for many years now. But yes, the bigger picture of how the tech will assist with the elderly is an unknown. We can only speculate as to what the outcome will be, but without certainty.

Physical assistance for the elderly will still require humans unless androids are created. I'm pretty certain that won't be by 2040. Many questions, many theories, but ultimately leading to only guesses for now.

Also, I see the future race between the US and China for supremacy being a very close two-horse race, but this cloud hanging over China could be a great influential factor as to who eventually wins. It'll be an interesting watch from our point of view, but for now purely speculation.

Thanks again for your informative and valuable input, solarguy.
