As always, we must welcome innovation and the benefits it brings us. But we must also remain committed to sustainable development, taking into account issues of inequality, human dignity and inclusiveness. Finally, this year’s top emerging technologies also remind us of the importance of political commitment. Take the example of the transition toward fuel-cell vehicles: it will require huge infrastructural adaptations and conversions. In fact, it’s estimated that if the . spent the same amount of money it took to put a person on the moon ( $100 billion in today’s dollars ), the shift to hydrogen-powered cars and refueling stations that pump hydrogen would be significantly eased. Often the technology itself is available but only a massive exercise of political will can bring about change.
