The speaker discusses how humans have always imagined the future, either utopically or dystopically, and presents the idea that multiple futures are possible. Using examples from the past, like the 1899 postcards predicting future technologies, the speaker illustrates how today's innovations were once considered science fiction. The concept of 'the cone of futures' is introduced, highlighting different types of futures: possible, plausible, preferable, and probable. The speaker, a strategic foresight consultant, analyzes current trends and creates scenarios to anticipate future developments. Practical applications discussed include cellular agriculture, which uses biotechnology to produce food without traditional farming methods, reducing water and land use. The speaker describes how microorganisms can produce proteins using hydrogen and carbon dioxide, potentially transforming CO2 into food, beverages, and even fuel. Examples include a U.S. startup producing vodka from CO2 and a Japanese innovation using electronic chopsticks to enhance food flavor without salt. The potential for sugar alternatives is also explored, with startups developing sweeteners that avoid blood sugar spikes. The speaker emphasizes the importance of making conscious choices today to shape the desired future, particularly in food consumption.
