are you kidding me? It's a problem as old as time.
This is not nuclear power though. The bigger problem is a scenario where AI increasingly acts like bacteria, doing things autonomously, things no one really understands, things we think are confusing and weird. And then just by chance, some bacteria end up in some human lung cells and they turn out to be an excellent place to grow and multiply. Why is this worse? Because weird shit does not seem threatening, and it almost always isn't, so nobody tries to stop it.
Also, the argument in the article seems to be "obviously AI development is not a particularly urgent global threat," and therefore these downsides (risk of collusion, misuse of state power, etc) are the most critical factors? I guess, uh, yeah, if there's no benefit to taking these actions we shouldn't take them.
