posts: 1476

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.

agriculture, energy and global development.	2020-12-07 15:28:13	2023-07-19 13:42:43	https://ourworldindata.org/wp-content/uploads/2023/03/Technological-Change.png	{ "toc": false, "bodyClassName": "topic-page" }	Almost every development that we cover on _Our World in Data_ is underpinned by some form of technological change. Medical innovations contributed to the decline of [child mortality](https://ourworldindata.org/child-mortality) and the improvements in [life expectancy](https://ourworldindata.org/life-expectancy). Improved [crop yields](https://ourworldindata.org/crop-yields) and reductions in hunger were made possible thanks to the advances in agricultural technologies. The long-term decline of [global poverty](https://ourworldindata.org/poverty) was primarily driven by increased productivity from technological change. Access to [energy](https://ourworldindata.org/energy), electricity, [sanitation](https://ourworldindata.org/sanitation), and clean water have transformed the lives of billions. Transport, telephones, and the [internet](https://ourworldindata.org/internet) have allowed us to collaborate on problems at a global level. Emerging technologies are often expensive and therefore initially limited to the richest in society. A key part of technological progress is making these life-changing, and often life-saving, innovations affordable for everyone. In many ways, technology has transformed our lives for the better. But these developments are not always positive: many of humanity’s largest threats – such as [nuclear weapons](https://ourworldindata.org/nuclear-weapons) and [potentially also](https://ourworldindata.org/ai-impact)[artificial intelligence](https://ourworldindata.org/artificial-intelligence) – are the result of technological advances.

Improved <a href=\"https://ourworldindata.org/crop-yields\">crop yields</a> and reductions in hunger were made possible thanks to the advances in agricultural technologies. The long-term decline of <a href=\"https://ourworldindata.org/poverty\">global poverty</a> was primarily driven by increased productivity from technological change. Access to <a href=\"https://ourworldindata.org/energy\">energy</a>, electricity, <a href=\"https://ourworldindata.org/sanitation\">sanitation</a>, and clean water have transformed the lives of billions. Transport, telephones, and the <a href=\"https://ourworldindata.org/internet\">internet</a> have allowed us to collaborate on problems at a global level.</p>\n\n\n\n<p>Emerging technologies are often expensive and therefore initially limited to the richest in society. A key part of technological progress is making these life-changing, and often life-saving, innovations affordable for everyone.</p>\n\n\n\n<p>In many ways, technology has transformed our lives for the better. But these developments are not always positive: many of humanity\u2019s largest threats \u2013 such as <a href=\"https://ourworldindata.org/nuclear-weapons\">nuclear weapons</a> and <a href=\"https://ourworldindata.org/ai-impact\">potentially also</a> <a href=\"https://ourworldindata.org/artificial-intelligence\">artificial intelligence</a> \u2013 are the result of technological advances.

<div class="wp-block-columns front-matter"> <div class="wp-block-column" id="introduction"> <p>Almost every development that we cover on <em>Our World in Data</em> is underpinned by some form of technological change. </p>   <p>Medical innovations contributed to the decline of <a href="https://ourworldindata.org/child-mortality">child mortality</a> and the improvements in <a href="https://ourworldindata.org/life-expectancy">life expectancy</a>. Improved <a href="https://ourworldindata.org/crop-yields">crop yields</a> and reductions in hunger were made possible thanks to the advances in agricultural technologies. The long-term decline of <a href="https://ourworldindata.org/poverty">global poverty</a> was primarily driven by increased productivity from technological change. Access to <a href="https://ourworldindata.org/energy">energy</a>, electricity, <a href="https://ourworldindata.org/sanitation">sanitation</a>, and clean water have transformed the lives of billions. Transport, telephones, and the <a href="https://ourworldindata.org/internet">internet</a> have allowed us to collaborate on problems at a global level.</p>   <p>Emerging technologies are often expensive and therefore initially limited to the richest in society. A key part of technological progress is making these life-changing, and often life-saving, innovations affordable for everyone.</p>   <p>In many ways, technology has transformed our lives for the better. But these developments are not always positive: many of humanity’s largest threats – such as <a href="https://ourworldindata.org/nuclear-weapons">nuclear weapons</a> and <a href="https://ourworldindata.org/ai-impact">potentially also</a> <a href="https://ourworldindata.org/artificial-intelligence">artificial intelligence</a> – are the result of technological advances. To mitigate these risks, good governance can be as important as the technology itself.</p>   <p>On this page, you can find our data, visualizations, and writing on many of the most fundamental technological changes that have shaped our world.</p> </div>   <div class="wp-block-column"> <div class="wp-block-group related-topics"> <p>Related topics</p>   <ul><li><a href="https://ourworldindata.org/artificial-intelligence">Artificial Intelligence</a></li><li><a href="https://ourworldindata.org/space-exploration-satellites">Space Exploration and Satellites</a></li><li><a href="https://ourworldindata.org/internet">Internet</a></li><li><a href="https://ourworldindata.org/light">Light at Night</a></li></ul> </div> </div> </div>     <div class="wp-block-group wp-block-research-and-writing"> <h2 id="research-writing">Research & Writing</h2>   <h4>Key articles on Technological Change</h4>     <p>Max Roser</p>     <p>Max Roser</p>     <p>Max Roser</p>     <p>Hannah Ritchie</p>      <h4>Artificial Intelligence (AI) and communication technologies</h4>     <p>Max Roser</p>     <p>Max Roser</p>     <p>Esteban Ortiz-Ospina</p>     <p>Esteban Ortiz-Ospina</p>     <h4>Energy and agricultural technologies</h4>     <p>Max Roser</p>     <p>Hannah Ritchie</p>     <p>Hannah Ritchie</p>     <p>Hannah Ritchie</p>     <h4>Concepts of technological change</h4>     <p>Max Roser and Hannah Ritchie</p>     <p>Max Roser</p>    </div>

Technological change underpins so many of the developments we've seen in health, agriculture, energy and global development.

Almost every development that we cover on _Our World in Data_ is underpinned by some form of technological change. Medical innovations contributed to the decline of [child mortality](https://ourworldindata.org/child-mortality) and the improvements in [life expectancy](https://ourworldindata.org/life-expectancy). Improved [crop yields](https://ourworldindata.org/crop-yields) and reductions in hunger were made possible thanks to the advances in agricultural technologies. The long-term decline of [global poverty](https://ourworldindata.org/poverty) was primarily driven by increased productivity from technological change. Access to [energy](https://ourworldindata.org/energy), electricity, [sanitation](https://ourworldindata.org/sanitation), and clean water have transformed the lives of billions. Transport, telephones, and the [internet](https://ourworldindata.org/internet) have allowed us to collaborate on problems at a global level. Emerging technologies are often expensive and therefore initially limited to the richest in society. A key part of technological progress is making these life-changing, and often life-saving, innovations affordable for everyone. In many ways, technology has transformed our lives for the better. But these developments are not always positive: many of humanity’s largest threats – such as [nuclear weapons](https://ourworldindata.org/nuclear-weapons) and [potentially also](https://ourworldindata.org/ai-impact)[artificial intelligence](https://ourworldindata.org/artificial-intelligence) – are the result of technological advances. To mitigate these risks, good governance can be as important as the technology itself. On this page, you can find our data, visualizations, and writing on many of the most fundamental technological changes that have shaped our world.

But these developments are not always positive: many of humanity\u2019s largest threats \u2013 such as <a href=\"https://ourworldindata.org/nuclear-weapons\">nuclear weapons</a> and <a href=\"https://ourworldindata.org/ai-impact\">potentially also</a> <a href=\"https://ourworldindata.org/artificial-intelligence\">artificial intelligence</a> \u2013 are the result of technological advances. To mitigate these risks, good governance can be as important as the technology itself.</p>\n\n\n\n<p>On this page, you can find our data, visualizations, and writing on many of the most fundamental technological changes that have shaped our world.</p>\n</div>\n\n\n\n<div class=\"wp-block-column\">\n<div class=\"wp-container-65e6e28295a93 wp-block-group related-topics\">\n<p>Related
