April 8 (Reuters) - Tesla Chief Executive Elon Musk on Monday said artificial intelligence that was smarter than the smartest human probably would be developed next year, or possibly the next.

In a wide ranging interview on X spaces that had multiple technology glitches, Musk, whose companies include AI startup XAI, also told Norway wealth fund CEO Nicolai Tangen that artificial intelligence was constrained by the availability of electricity.
