All good. I just keep seeing this all the time about batteries, simply because most of the technological advances are slow, cumulative, aggregate, and largely invisible to consumers. Then people complain about how none of these advances ever make it to market while ignoring, for example, how many pounds old, barely capable cell phones were compared to the functionality of smartphones these days that can run for a full day on a battery a fraction of the size we had for those old behemoths, all apparently without any of those breakthroughs making it to market. I mean, look at the first cell phone in this article. I suspect some advancements occurred in batteries between then and now.
