Almost all of the movie's technology feels like science fiction. The plot revolves around killer nanobots that can assassinate specific people or groups based on their DNA. We also see a variety of Bond gadgets that don't seem realistic at our current level of technology. As unrealistic as all this technology is, it will likely seem outdated in a couple of decades. For example, I think that the future of biotechnology won't be nanobots, which in science fiction are typically presented as all-powerful capable of doing almost anything, but instead will be actual biotechnology using genetics and microorganisms.
There is a scene early in the film where a Bond car is shown to be bulletproof, despite having normal-looking windows. Real bulletproof glass can be up to 3.5 inches thick. I would not expect thin car windows to withstand a massive barrage of bullets as they do in this scene.Daniel Craig is great as Bond. Christoph Waltz has a really good but all too brief scene as Blofeld. Lashana Lynch is good as a female 007, but Rami Malek steals the show as the new creepy villain. He will be playing Robert Oppenheimer in a 2023 film.
