06:02:00 +07:00 Tools for thought: the first 300,000 years - A super high level summary of some of the big technological innovations that humans have made which have resulted in our modern world. It's funny to me because I've been preparing something similar in my spare time recently. I was focusing on science whereas this focusses on actual inventions. Two sides of the same coin in a way. Anyhow worth reading if you are at all interested in history and culture and perhaps the future. # subconscious.substack.com
