I love that curve and thinking about how it maps to other &quot;futuristic&quot; tech.<p>Space flight is probably coming out of its trough of disillusionment right now, as is renewable energy (solar&#x2F;wind).<p>Genetic engineering is deep in the trough with anti-GMO sentiment, the supposed failure of the human genome project to pay out, and general paralysis in the field. Nuclear power is also probably still deep in the trough with Fukushima and us still being stuck on overgrown submarine reactors.
