Actually, hot and hungry is a perfectly natural evolution with technology, it's called the "Rebound Effect", and it's the phenomenon in which technological gains in efficiency are met with anincrease in power usage instead of a decrease, and it's been observed in every basic industry and in every application. A good way of demonstrating it is with work.... Technology and automation have made humans more productive than ever, but has this resulted in the need to perform less work? Or even a steady state in which the same amount of work is performed year over year? No, on average people are working more than ever despite being more productive than ever, and the same can be said for power and energy usage. In fact, the rebound effect is held up as one of the primary examples of why technological development will never solve our energy or environmental crisis.
We can argue about the original impetus behind this trend, but the result is that consumers and enthusiasts alike have been conditioned to expect ever increasing performance gains. Just like a logarithmic equation whose graph flattens out as it approaches zero, obtaining those gains has been increasingly difficult with node advancements and architectural improvements, so they're obviously leaning on increased power consumption as this problem intensifies. Just think of the culture of marketing and how it has not evolved to deal with a product that isn't any more powerful than the last generation, but uses 40% less power... They wouldn't know how to sell it, and consumers wouldn't buy it.... Just look at the survey this website did on power usage in PC components which I think it's still doing on the homepage, "environmental concern" is the least chosen answer. This is the inherent nature and problem of consumerism.
