Let's create a detailed timeline of the near-future technological and scientific development of the world. I think this would be a useful tool for anyone wanting to write realistic near-future sci-fi, in addition to being interesting in its own right. Rules: - One discovery per post. - Assume the current rate of technological advance remains more or less constant. - Avoid bringing in geopolitical elements which would shift the timeline. So no civilisational collapse, no sudden increases or decreases in the world's scientific output, no global crises like asteroids that would shift the world's focus. - The idea here is to be realistic, so no going off on wild speculative tangents that have no basis in current scientific understanding. Posting format: Year - Area Description Example: 2022 - Energy First commercial lithium-air batteries come to market. With an energy density similar to gasoline, they will greatly increase the range of electric cars and also extend the battery life of consumer electronics.
