prompter: If we reached 1 billion people on earth not that long ago, why people didn't make as much kids as now ?

assistant: The world's population has increased dramatically over the past few centuries, from around 1 billion people in 1800 to over 7 billion people today. The reasons for this growth are complex and multifaceted, and can be attributed to a variety of factors including advances in medicine, improved sanitation and hygiene, and increases in food production and distribution.

However, it's important to note that the rate of population growth has not been consistent over time, and has been influenced by a variety of social, economic, and cultural factors. In general, as societies become more developed and prosperous, fertility rates tend to decline, as people have fewer children and invest more resources in each child's upbringing.

In the past, when resources were scarce and mortality rates were high, it was common for people to have larger families to ensure that at least some of their children would survive to adulthood and be able to support the family. However, as living conditions improved and infant mortality rates decreased, there was less need for large families, and birth rates began to decline.

Additionally, social and cultural changes have also played a role in declining fertility rates. For example, as women have gained more opportunities for education and employment, they have often chosen to delay or forego having children in order to pursue other goals. Moreover, the widespread availability of contraception and family planning services has made it easier for people to control their reproductive choices and have smaller families if they so choose.

In summary, while population growth has been influenced by a variety of factors over time, including advances in medicine and increases in food production, declining fertility rates as societies become more developed and prosperous have played a major role in slowing population growth in recent decades.

prompter: What long term changes in society will the widespread availability in contraception cause? As well as women gaining more opportunities for education and unemployment? If those people don't reproduce, won't the surviving people be the ones that don't seek education and employment, and the ones that don't use contraception?

assistant: Sorry, your question confused me. Do you mean to say that people made less children historically and why they make more now, or the other way around?

prompter: I mean why people are making more kids now.

assistant: It depends where you're talking about. In areas with HDI scores, typically areas with higher female employment and autonomy, people are having less children. In areas with low development, populations will grow at an exponential rate as children continue have children of their own at a rate higher than replacement.

prompter: But with how hypersexualized things have gotten in the last few decades, wouldn't it make sense that people would be way more eager to have kids?

assistant: The rate of population growth in an open system is exponential. While modeling the earth as an open system and modelling human population as a simple population model is, well, simplistic, it is sufficient to understand why there are more babies born now than in the past. In an exponential system, the rate of growth increases with time. Thus, the larger the population, the faster the population grows.

It is easy to understand why population growth is exponential: creating a new member of the population requires two original members of the population. The birthrate is therefore dependent on the number of members in the population. Additional births increase the population size, which increases the birth rate.

Populations tend to follow this exponential model until they hit the carrying capacity of their environment; then, the growth rate slows.

prompter: I'm pretty sure I saw that the growth rate of Earth's population was slowing down though. Have we hit carrying capacity? If we wanted, I feel like we could make more farms, roads, etc., to sustain more people.
