Questions are not a problem, obligation to answer is a problem. Criticism is not a problem, implicit blame for ignoring it is a problem. Availability of many questions makes it easier to find one you want to answer.
Incidentally, understanding/verifying/getting-used-to/starting-to-track the answer (for those who care about the question) is often harder than writing an answer (for those whose mind was already prepared to generate it).
Energy requirements are an issue locally, when you need to build a single large datacenter on short notice. With distributed training, you only need to care about a global energy budget. The world generates about 20,000 GW of power, the H100s fueled with 1% of that would cost trillions of dollars.
