He didn't have more knowledge than we do now, 100 years, trillions of research dollars and millions of engineers later. He had a very amazing and intuitive sense of electricity, mechanics and physics in general, as well as an eidetic memory but it's not like he was conjuring mystical secrets out of the aether, any more than, say, OpenAI is today. And that's about how his inventions were received: with surprise that such things were possible, followed by credulity and wild predictions over where it might go, mostly relayed by people who didn't understand the technology.

Electricity simply doesn't provide a practical mass destructive capacity in the way that, say, the strong nuclear force does. However, from the breakneck rate of electrical technology from the 1890s onwards, you could see why an extrapolation of those capabilities could make it plausible that it could eventually get there.

While it's no doubt true that he didn't have substantially more knowledge than we do now, it's important to consider that some areas he was working in have only recently come to bear similar fruit. Specifically wireless power transmission, for example, was patented by him in 1916 and only in recent years were similar effects actually put into practice on a small scale (functioning in a nearly identical way as described in the patent).

There's been plenty of times in history something has been lost or buried due to the death of the creator or societal / political pressures.

Consider the EV1 and the legal fight against California's Zero Emissions legislation, some 20 years before Tesla Motors would shake things up.

So what? Perpetual motion machines, and a lot of other junk that never could work, have also been patented both before and since. Not only Einstein but also a lot of idiots have worked in patent offices around the world.
