This article offers a view of the prospects of nuclear fusion as a sustainable energy source, with a focus on magnetic confinement fusion and tokamaks. It highlights the key theme of integration and presents the EUROfusion programme as a model for coordinated fusion R&D in Europe while stressing the need for public–private partnerships to bridge the gap between laboratory innovation and industrial implementation. A crucial element is human capital development, i.e. the training of a new, diverse generation of scientists, engineers, and technicians. A broader educational effort is called for, with industry–academia collaboration, hands-on training, and mechanisms to retain and transfer knowledge from legacy projects such as JET.
