Reading about all of the cost savings analysis and discussions. Then about the number of data centers globally, I started wondering about the longevity of the products we are all so eagerly awaiting to be commercialized. I have learned so much over the last couple of years reading this wonderful board and I hope this doesn't offend anyone by me asking to be educated . I would just like to understand more about the life SPAN of these products if they don't produce so much heat and they don't require as much electricity. How does said lifespan play into your thoughts on the profit margin? Thanks in advance.
