It’s a techground morning for Japan — semiconductor news is the loudest thread, with diamond semiconductors advancing toward practical use and Intel potentially circling back to memory forty years after exiting DRAM. On the softer side, AI coding culture is creating new overhead for junior devs and the engineers mentoring them. Meanwhile the crypto beat keeps running: Ionic Digital’s pivot from mining rigs to AI landlord, and MetaPlanet’s stock surge on fresh BTC speculation. Drought conditions lingering in the background serve as a reminder that Japan’s infrastructure stress isn’t purely digital.
