1. We have at least one fusion plant I know of, the UK Joint Torus, which I know have been operating for decades. It just consumes more power than it generates. But Asimov suggests one or two, which is strikingly accurate.
2. We could probably make radio-decay batteries (maybe not AA size, but car batteries running on Thorium or some such, albeit an extremely expensive containment for something running so hot). We probably just don't do it because the radiation risks are too high.
And I'd count airport conveyors as moving sidewalks. Or just the complexity of baggage carrying systemes in those airports, lend that we easily have the technoloy to create weather resistant rotary motor systems as sidewalks, but like Asimovs suggestions of underground housing, cost is the bigger prohibitor than technology.
Also, I don't think the degree of boredom he touches on has occured. Consumerism and the wealth concentration in the US has kept people needing to maintain 40 hour work weeks where productivity is magnitudes higher. We produce vastly more, but work as much as ever. Back in the 60s the sentiment was that 21st century Americans might have 10 hour work weeks.
