Women organizations in 1970s started investigation workplace hazards and thought they are poisonous. However before 1970s people often associated workplace hazards with manufacturing jobs (male) and not office jobs. Then some organization came in and did research and testing with advanced machines and found that there was no evidence to show there are any poisonous material at work.

Marine mammals are prone to compression disease (nitrogen bubbles in bones when rising from deep sea to surface - blocks blood circulation and can lead to death). There was this animal (can't remember the name, some deap sea crocodile / reptile) that existed in Jurassic era (earlier) and post jurassic era (later), scientists thought that animal would have developed some sort of mechanism to deal with the compression disease, but research found that the fossils revealed the earlier ancesters of this animal didn't die from this disease but the later generations (Jurassic era) did.
It was then described that the animal often died from compression disease later on in history because there were other giant crocodile and sea sharks acting as predators so they surfaced more often in Jurassic era, because they surfaced more often, they died frequently of compression disease (caused by surfacing from deep sea)

Technology developed in history:
1. Constrained by hardware
2. There is a gap between capability of the computer and how engineers envison how their applications can make the computer function (utility), and the profitability in the industry is driven by the gap between the hardware limitation and utility limitation. Whoever can exploit the gap can make money.
3. Traditional view is that profit is when a company manufactures hardware, but author says it lies in the software and application side of tech.
