Acharya Prashant explains that people often believe that because human intelligence and desire are limitless, the human race is destined for endless expansion. They take inspiration from history, noting that humanity has always been inventing and progressing, never stopping at one level of development. From this historical trend, they extrapolate that the future will continue in the same manner. However, the speaker points out that they forget to factor in a crucial variable: the carrying capacity of the Earth. He argues that until now, humanity has been able to expand materially in terms of both consumption and population because the planet could afford it. But we have now reached a special point in history where this is no longer possible, regardless of technological advancements. The speaker refutes the idea that more efficient technology can solve the problem of resource scarcity. He explains that as a technology becomes more efficient, its use becomes more widespread, which paradoxically leads to an increase in net material consumption rather than a decrease. Therefore, the notion that we can continue expanding materially forever with better technologies is flawed. He also addresses the argument that more material growth is the solution to pollution, often citing Europe as an example. He clarifies that while Europe is clean today, this was achieved at a cost to the rest of the world, representing a 'local optimum' at the expense of a 'global optimum'. The speaker concludes that the logic of using more consumption to solve the world's problems is misplaced. He asserts that the mind of the economist must now stop thinking solely in the language of consumption, and that economics and spirituality must converge. The measure of human wellness can no longer be human consumption. Instead, a new internal model of wellness is needed. The questions should shift from whether a person has basic material means to whether they are peaceful, understand life, know love, and can remain stable amidst psychological turbulence. These internal states, he suggests, are what will now define and determine true wellness.
