There is no analysis of the funding of science, at present or in the future. There is nothing about the future of weapons technology and its effect on the armaments industry. Nor is there any analysis of the financial dependence of much of science on the military-industrial complexes of the superpowers. These omissions emphasise the benevolent image of science presented by the book. If its history is anything to go by, the future of science will be more messy and complex, and the costs in financial, ecological and human terms more extensive and traumatic than Kaku depicts.
Science is made and funded by people.
Kaku does examine some of the dangers and trade-offs , but his triumphalist view of science tends to justify the unpleasant means in terms of a glorious end. Science is an immense array of measured but incomplete models of understanding. It is a powerful tide of theories, based on research and experiment, constantly being developed and superseded by others. As geneticist Steve Jones puts it, there is no limit to its enquiries, and no explanation is ever complete . Phrases such as the laws of nature are misleading abstractions.
