If you watch videos from the 1980s about computers, it's all the same unfulfilled promises as "AI" now: we will work less, everything will be more plentiful, easier, autonomous robots, natural language perfected, computer vision perfected.
The demand for hardware and programmers has grown exponentially and we're still being promised the same breakthroughs 45 years later. We could probably have the same productivity and the same civilization with maybe a tenth of the data centers.
