Think back to the 2021-2022 pandemic-triggered supply chain chaos, when the media widely reported that car companies, for example, were all having very painful experiences with parking lots full of $50k trucks they couldn't sell due to a lack of $5 chips. At the time I saw some of Sam's videos (I think I originally found them here on HN), and I had a big question: If a hobbyist can build 1970's era chips for ~$10k in his garage, and Intel can build 2020's era chips for ~$10B in state-of-the-art factories, why doesn't someone start a startup building 1990's era chips in a ~$10M facility? I'd assume Atomic Semi is that startup :)
