This table contains the full text for all our old WORDPRESS content in html form. The format is a bit odd as it represents a direct copy from wordpress content that includes a lot of wordpress specific comments that carry some meaning in terms of layout instructions etc.. The html in the content column can thus be rendered as is but will not look identical to the way it looks on our website as several post processing steps are not applied yet. The content should work though as a readable approximation for every post. For easy searching etc, a markdown copy of the content is available in the markdown column. If you want to query all posts (both wordpress and gdocs), use the posts_unified table or the posts_unified_with_content view.

This article draws on data and research discussed in our entry on [Artificial Intelligence](https://ourworldindata.org/artificial-intelligence). Artificial intelligence (AI) technology has steadily become more powerful over the course of the last decades and in recent years it has entered our world in many different domains. In a companion article – [the brief history of artificial intelligence](https://ourworldindata.org/brief-history-of-ai) – I document this development. This was achieved despite having relatively few resources. Until recently, investments in terms of capital and scientific efforts were small. In this article I highlight that this has very much changed in recent years. Corporate investment has increased and the scientific field has grown in size. Given how rapidly AI developed in the past, despite the limited resources, this should make us expect AI technology to continue to become more powerful in the coming decades. ## Investments into AI The first chart looks at corporate investment over time.{ref}It is not obvious how to adjust a time-series of AI investments for inflation, and we debated it at some length within the team. Reporting it in nominal prices (as some do) means it makes little sense to compare observations across time and is therefore not very helpful. To make comparisons over time possible one has to take into account that prices change. It would be straightforward to adjust the time series for price changes if we knew the prices of the specific goods and services that these investments purchased. This would make it possible to calculate a volume measure of AI investments, and it would tell us how much these investments bought. But such a metric is not available. (While a comprehensive price index is not available, we know that the cost for some crucial AI technology has fallen rapidly in price. For example, it has become much cheaper to train an AI system.) In the absence of a comprehensive price index that captures the price of AI-specific goods and services, one has to rely on one of the available metrics for the price of a bundle of goods and services. In the end we decided to use the US Consumer Price Index (CPI). The US CPI does not provide us with a volume measure of AI goods and services, but it does capture the opportunity costs of these investments. The inflation adjustment of this time series of AI investments therefore lets us understand the size of these investments relative to whatever else these sums of money could have purchased.{/ref} Until recently, private sector investment was relatively low. But, especially from 2018 onwards, it has increased rapidly. Investments in 2021 were about 30-times larger than just eight years earlier. <Chart url="https://ourworldindata.org/grapher/corporate-investment-in-artificial-intelligence-by-type"/> ## Research and the labor market The four following visualizations show that the trends for AI research efforts and the labor market are similar. Just a decade ago the field was much smaller than it is today. Since then the number of research publications on artificial intelligence has doubled, and AI conferences have become much larger events. This is what the first two charts show. The third chart documents the increasing importance of AI skills in the labor market. The last chart shows the specialty of computer science PhD students in the US. With an increasing number of students in the field, the number of researchers and research output is set to increase further in years to come. Additionally, AI itself is contributing to the development of AI: Researchers are beginning to find ways for AI itself to contribute to the development of AI.{ref}One early example for this is [Neural architecture search](https://en.wikipedia.org/wiki/Neural_architecture_search).{/ref} <Chart url="https://ourworldindata.org/grapher/annual-scholarly-publications-on-artificial-intelligence"/> <Chart url="https://ourworldindata.org/grapher/attendance-major-artificial-intelligence-conferences"/> <Chart url="https://ourworldindata.org/grapher/share-artificial-intelligence-job-postings"/> <Chart url="https://ourworldindata.org/grapher/number-new-cs-phds-us-by-specialty"/> ## Conclusion The developments in the past happened despite the fact that funding and brainpower dedicated to AI were quite limited. As these charts have shown, this has changed. Across a range of metrics, the resources dedicated to AI development have increased substantially. The fact that the field advanced with relatively small resources, and now has much larger resources at its disposal – leading to [rapid advances](https://ourworldindata.org/brief-history-of-ai) in the last few years – is one reason why I expect AI technology to continue to develop rapidly and to exert a larger and larger influence on our world. _Continue reading on Our World in Data:_ [AI timelines: What do experts in artificial intelligence expect for the future?](https://ourworldindata.org/ai-timelines) Acknowledgements: I would like to thank Julia Broden, Charlie Giattino, Joe Hasell, and Edouard Mathieu for their helpful comments to drafts of this essay and the visualizations.

In the past, relatively few researchers were working on AI technology and there was little commercial interest and funding. Now, the available resources have increased substantially. We should expect that the field continues to advance rapidly.

Our World in Data presents the data and research to make progress against the world’s largest problems. This article draws on data and research discussed in our entry on **[Artificial Intelligence](https://ourworldindata.org/artificial-intelligence)**. Artificial intelligence (AI) technology has steadily become more powerful over the course of the last decades and in recent years it has entered our world in many different domains. In a companion article – [the brief history of artificial intelligence](https://ourworldindata.org/brief-history-of-ai) – I document this development. This was achieved despite having relatively few resources. Until recently, investments in terms of capital and scientific efforts were small. In this article I highlight that this has very much changed in recent years. Corporate investment has increased and the scientific field has grown in size. Given how rapidly AI developed in the past, despite the limited resources, this should make us expect AI technology to continue to become more powerful in the coming decades. ## Investments into AI The first chart looks at corporate investment over time.{ref}It is not obvious how to adjust a time-series of AI investments for inflation, and we debated it at some length within the team. Reporting it in nominal prices (as some do) means it makes little sense to compare observations across time and is therefore not very helpful. To make comparisons over time possible one has to take into account that prices change. It would be straightforward to adjust the time series for price changes if we knew the prices of the specific goods and services that these investments purchased. This would make it possible to calculate a volume measure of AI investments, and it would tell us how much these investments bought. But such a metric is not available. (While a comprehensive price index is not available, we know that the cost for some crucial AI technology has fallen rapidly in price. For example, it has become much cheaper to train an AI system.) In the absence of a comprehensive price index that captures the price of AI-specific goods and services, one has to rely on one of the available metrics for the price of a bundle of goods and services. In the end we decided to use the US Consumer Price Index (CPI). The US CPI does not provide us with a volume measure of AI goods and services, but it does capture the opportunity costs of these investments. The inflation adjustment of this time series of AI investments therefore lets us understand the size of these investments relative to whatever else these sums of money could have purchased.{/ref} Until recently, private sector investment was relatively low. But, especially from 2018 onwards, it has increased rapidly. Investments in 2021 were about 30-times larger than just eight years earlier. <Chart url="https://ourworldindata.org/grapher/corporate-investment-in-artificial-intelligence-by-type"/> ## Research and the labor market The four following visualizations show that the trends for AI research efforts and the labor market are similar. Just a decade ago the field was much smaller than it is today. Since then the number of research publications on artificial intelligence has doubled, and AI conferences have become much larger events. This is what the first two charts show. The third chart documents the increasing importance of AI skills in the labor market. The last chart shows the specialty of computer science PhD students in the US. With an increasing number of students in the field, the number of researchers and research output is set to increase further in years to come. Additionally, AI itself is contributing to the development of AI: Researchers are beginning to find ways for AI itself to contribute to the development of AI.{ref}One early example for this is [Neural architecture search](https://en.wikipedia.org/wiki/Neural_architecture_search).{/ref} <Chart url="https://ourworldindata.org/grapher/annual-scholarly-publications-on-artificial-intelligence"/> <Chart url="https://ourworldindata.org/grapher/attendance-major-artificial-intelligence-conferences"/> <Chart url="https://ourworldindata.org/grapher/share-artificial-intelligence-job-postings"/> <Chart url="https://ourworldindata.org/grapher/number-new-cs-phds-us-by-specialty"/> ## Conclusion The developments in the past happened despite the fact that funding and brainpower dedicated to AI were quite limited. As these charts have shown, this has changed. Across a range of metrics, the resources dedicated to AI development have increased substantially. The fact that the field advanced with relatively small resources, and now has much larger resources at its disposal – leading to [rapid advances](https://ourworldindata.org/brief-history-of-ai) in the last few years – is one reason why I expect AI technology to continue to develop rapidly and to exert a larger and larger influence on our world. _Continue reading on Our World in Data:_ [AI timelines: What do experts in artificial intelligence expect for the future?](https://ourworldindata.org/ai-timelines) **Acknowledgements:** I would like to thank Julia Broden, Charlie Giattino, Joe Hasell, and Edouard Mathieu for their helpful comments to drafts of this essay and the visualizations. **Appendix** Additional charts on the rise of investments into AI technology
