Factor 09 of 9
Technological factors
Lack of access to basic tools, and harmful side effects of the technologies people do have, such as misinformation and job displacement.
Barriers within this factor
Each barrier has its own page with the evidence and sources behind it.
- 1The digital divide
ITU's Facts and Figures 2025 estimates 6 billion people use the internet, but 2.2 billion remain offline. The gaps are sharp.
Evidence and sources (3 evidence points, 6 experimental methods)
- 2Electricity access
Electricity access is still incomplete, mostly in sub-Saharan Africa.
Evidence and sources (3 evidence points, 4 experimental methods)
- 3Slow technology diffusion
Comin and Hobijn (2010) studied the spread of 15 technologies across 166 countries over two centuries.
Evidence and sources (3 evidence points, 5 experimental methods)
- 4Technology without supporting systems
Providing devices does not by itself improve learning, while technology designed around how children learn can work well.
Evidence and sources (3 evidence points, 4 experimental methods)
- 5Misinformation
Vosoughi, Roy, and Aral (2018) studied about 126,000 verified true and false news stories shared on Twitter from 2006 to 2017.
Evidence and sources (4 evidence points, 5 experimental methods)
- 6Digital technology and adolescent wellbeing (debated)
Orben and Przybylski (2019) analyzed three large datasets totaling 355,358 adolescents.
Evidence and sources (2 evidence points, 4 experimental methods)
- 7Automation and job displacement
Acemoglu and Restrepo (2020) studied industrial robots in U.S. labor markets.
Evidence and sources (2 evidence points, 5 experimental methods)
Evidence strength
Main findings behind this page, grouped by the strength ratings, from strongest to weakest. Each tier lists the findings that received that rating.
| Strength | Findings |
|---|---|
| Strong | One Laptop per Child, short and long term. |
| Moderate | The digital divide and electricity access (agency estimates). The spread of false news. Slow technology diffusion. The size of the association between technology use and adolescent wellbeing. Robots and employment. |
| Limited | Mindspark beyond the students studied. |
| Contested or debated | Whether digital technology use harms adolescent wellbeing. Effects of artificial intelligence on employment, which are still emerging. |
Actions that can reduce these barriers
Proven actions for the technological barriers have not yet been researched. Each barrier below lists proposed and experimental methods only, with the stage labels and ratings explained below.
Proposed and experimental methods
Each barrier also has a list of proposed and experimental methods. It covers methods that are proposed, under trial, approved in some places but not widely used, or tried and then failed or reversed, so readers can see what is being tested. Each method has a stage label and an evidence rating in parentheses. The stage labels are Theoretical (proposed but not yet tested as an intervention), Early trial (small or first studies), Large trial (large randomized or field trials), Approved but not scaled (legally approved or running in some places but not widely adopted), In wide use (widely adopted but newly tested or questioned), Sold commercially without trials (used for polygenic embryo screening), and Failed or reversed (tested and shown not to work, or adopted and then withdrawn). The word contested is added where the evidence is disputed. Failed, reversed, and unhelpful methods are listed last and begin with "Failed," "Reversed," or "Not shown to help." A stage label shows how far a method has progressed, not whether it works, and the rating shows the strength of the evidence.
Ideal conditions that counter this factor
The growing burden of knowledge
What the evidence shows
Jones (2009) found that as knowledge accumulates, age at first invention, specialization, and teamwork all rise. Bloom et al. (2020) found research productivity is declining.
Ideal:
- Faster ways to bring learners to the frontier
- Structures that combine specialists
- Tools that shorten mastery time, where some researchers suggest AI may help, which is speculative
Evidence strength: Moderate. The trend is moderate to strong, and solutions are not yet established.
In the pioneer cases
Statements from the pioneer records that this site classifies under the technological factor. The classification is this site's.
| Pioneer | Effect | Statement |
|---|---|---|
| Albert Einstein | Helped | Technical exposure. His father and uncle ran an electrical engineering business. |
| Albert Einstein | Note | Galison's hypothesis. Galison (2003) argued that reviewing clock-synchronization patents may have shaped his thinking on simultaneity. This is a plausible hypothesis, not an established fact. |
| Jonas Salk | Helped | Others' discoveries. In 1949 Enders, Weller, and Robbins grew poliovirus in tissue culture. |
| Norman Borlaug | Helped | Others' work. He crossed Norin 10, a Japanese dwarf wheat from Orville Vogel, with his rust-resistant varieties. |
| Tu Youyou | Helped | Collaboration. Other institutes helped determine artemisinin's chemical structure using X-ray crystallography. |
| Fritz Haber | Barrier | Making ammonia directly from atmospheric nitrogen in a practical way had long eluded chemists. His process required pressures of 150 to 200 atmospheres and temperatures of about 500 degrees Celsius. |
| Fritz Haber | Helped | Carl Bosch and Alwin Mittasch. Bosch led the industrial scale-up and Mittasch the catalyst work. The first ammonia synthesis plant opened at Oppau in 1913. |
Key figures
| Measure | Value | Source |
|---|---|---|
| Internet users and people offline | 6 billion use the internet and 2.2 billion remain offline. 96% of those offline live in low- and middle-income countries | ITU Facts and Figures 2025 |
| Share online by group, 2025 | High-income countries 94%, low-income countries 23%, urban areas 85%, rural areas 58%, men 77%, women 71% | ITU (2025) |
| 5G coverage, high-income vs. low-income countries | 84% vs. 4% | ITU (2025) |
| People without basic electricity, 2024 | About 655 million, leaving about 92% of the world with basic access. 89 million people gained access that year, but population growth meant the total fell by only about 11 million. About 86% of those without power (563 million people) live in sub-Saharan Africa | Tracking SDG7 (2026) |
| People lacking clean cooking | About 2 billion | Tracking SDG7 (2026) |
| Average lag from invention to adoption, 15 technologies in 166 countries over two centuries | 45 years, with wide variation. Newer technologies have been adopted faster than older ones | Comin and Hobijn (2010) |
| Income differences accounted for by differences in technology adoption | At least 25% of per capita income differences | Comin and Hobijn (2010) |
| One Laptop per Child, Peru (318 rural schools) | Computers per student rose from 0.12 to 1.18, with no evidence of effects on math or language test scores after 15 months | Cristia et al. (2017) |
| One Laptop per Child, long-term follow-up | No significant effects on academic performance, school completion, or university enrollment, and some evidence of slower grade progression. Computer skills improved, but teachers' digital skills did not, and classroom computer use was low | Cueto et al. (2025) |
| Mindspark gains after 4.5 months | 0.37 SD math, 0.23 SD Hindi | Muralidharan et al. (2019) |
| Spread of true and false news on Twitter, 2006 to 2017 | About 126,000 verified stories studied. False news spread significantly farther, faster, deeper, and more broadly than true news in every category | Vosoughi et al. (2018) |
| Digital technology use and adolescent wellbeing (debated) | Three datasets totaling 355,358 adolescents. The association was negative but small, explaining at most 0.4% of the variation in wellbeing | Orben and Przybylski (2019) |
| Robots: employment and wage effect per robot per 1,000 workers | -0.2 percentage points, -0.42% | Acemoglu and Restrepo (2020) |
