Key takeaways from "21 Lessons for the 21st Century" by Yuval Noah Harari

Introduction

In today's fast-changing world, we face many big challenges—from technology and fake news to climate change and political uncertainty. In "21 Lessons for the 21st Century," Yuval Noah Harari breaks down these issues into 21 short chapters. This blog gives you a clear and simple summary of each lesson.

Part I: The Technological Challenge

Theme: How new technology is changing jobs, freedom, and fairness

1. Disillusionment
Many people are losing faith in the idea that the world is getting better. We need to be honest about our confusion and take time to understand what's really happening.

2. Work
Robots and AI may take over many jobs. In the future, learning new skills and being emotionally strong will be very important.

3. Liberty
Big companies and governments are watching us more than ever. If they control our data, they can control us.

4. Equality
The people who own data have a big advantage. If we don’t act, the gap between rich and poor will grow even more.

Part II: The Political Challenge

Theme: How we manage identity, nations, and global problems

5. Community
We may be connected online, but we still need real, face-to-face relationships.

6. Civilisation
Even though we come from different cultures, we’re part of one global civilisation. We need to work together.

7. Nationalism
Problems like pandemics and climate change need global cooperation. Nationalism alone isn’t enough.

8. Religion
Some people are using religion to push political ideas. We should use religion to guide our values, not divide people.

9. Immigration
Immigration raises difficult questions. We need honest talks and a spirit of compromise.

Part III: Despair and Hope

Theme: Dealing with fear, conflict, and finding hope

10. Terrorism
Terrorists want to scare us. But fear gives them more power than they deserve.

11. War
War is still possible. Human mistakes and foolishness can cause great harm.

12. Humility
No country or religion is perfect. Being humble helps us live in peace with others.

13. God
Using God’s name to justify hate or violence is wrong.

14. Secularism
Even non-religious people must be honest about their own mistakes and values.

Part IV: Truth

Theme: How to find truth in a world full of lies

15. Ignorance
We don’t know as much as we think. It’s okay to listen to experts and admit we don’t have all the answers.

16. Justice
Our old ideas of fairness may not work in a global world. We need new ways to think about justice.

17. Post-Truth
Fake news spreads fast today. We must learn to check facts and think carefully.

18. Science Fiction
Movies are fun, but they often give us the wrong idea about the future. Let’s focus on real issues.

Part V: Resilience

Theme: How to stay strong and find meaning in a confusing world

19. Education
We must teach kids how to think, not just memorize facts. They need to be curious and emotionally strong.

20. Meaning
Life doesn’t always follow a clear story. And that’s okay. It’s fine to live with questions.

21. Meditation
Being mindful helps us stay calm and focused. Harari says meditation helps him understand himself better.

Final Thoughts
"21 Lessons for the 21st Century" doesn’t give quick fixes. Instead, it encourages us to ask better questions. Whether you're thinking about the future of work, politics, or your personal life, Harari’s message is clear: Slow down. Think clearly. Be ready for change.

Stay open. Stay thoughtful. Stay aware.

Sitecore PowerShell Script to create all language versions for an item from en version

  We have lots of media items and our business wants to copy the data from en version of media item to all other language versions defined in System/Languages. This ensures that media is available in all the languages. So, we created the below powershell script to achieve the same -  #Get all language versions defined in System/Languages $languages = Get-ChildItem /sitecore/System/Languages -recurse | Select $_.name | Where-Object {$_.name -ne "en"} | Select Name #Ensuring correct items are updated by comparing the template ID  $items = Get-ChildItem -Path "/sitecore/media library/MyProjects" -Recurse | Where-Object {'<media item template id>' -contains $_.TemplateID} #Bulk update context to improve performance New-UsingBlock (New-Object Sitecore.Data.BulkUpdateContext) { foreach($item in $items){    foreach($language in $languages){ $languageVersion = Get-Item -Path $item.Paths.Path -Language $language.Name #Check if language versi...

Make Sitecore instance faster using Roslyn Compiler

When we install the Sitecore instance on local, the first load is slow. After each code deploy also, it takes a while for the Sitecore instance to load and experience editor to come up. For us, the load time for Sitecore instance on local machines was around 4 minutes. We started looking for ways to minimize it and found that if we update our Web.config to use Roslyn compiler and include the relevant Nugets into the project, our load times will improve. We followed the simple steps - Go to the Project you wish to add the NuGet package and right click the project and click 'Manage NuGet Packages'. Make sure your 'Package Source' is set to nuget.org and go to the 'Browse' Tab and search Microsoft.CodeDom.Providers.DotNetCompilerPlatform. Install whichever version you desire, make sure you note which version you installed. You can learn more about it  here . After installation, deploy your project, make sure the Microsoft.CodeDom.Providers.DotNetCompilerPlatform.d...

Experience of a first time Sitecore MVP

The Journey I have been working in Sitecore for almost 10 years now. When I was a beginner in Sitecore, I was highly impressed by the incredible community support. In fact, my initial Sitecore learning path was entirely based on community written blogs on Sitecore. During a discussion with my then technology lead Neeraj Gulia , he proposed the idea that I should start giving back to developer community whenever I get chance. Just like I have been helped by many developers via online blogs, stackoverflow etc., I should also try to help others. Fast forward a few years and I met  Nehemiah Jeyakumar  (now an MVP). He had a big archive of his technical notes in the form Sitecore blogs. I realized my first blog dont have to be perfect and it can be as simple as notes to a specific problem for reference in future. That's when I probably created my first blog post on Sitecore. At that time, I didn't knew about the Sitecore MVP program. Over the years, I gained more confidence to writ...

Clean Coding Principles in CSharp

A code shall be easy to read and understand. In this post, I am outlining basic principles  about clean coding after researching through expert recommended books, trainings and based on my experience. A common example to start with is a variable declaration like - int i  The above statement did not clarify the purpose of variable i. However,  the same variable can be declared as -  int pageNumber The moment we declared the variable as int pageNumber, our brain realized that the variable is going to store the value for number of pages. We have set the context in our brain now and it is ready to understand what the code is going to do next with these page numbers. This is one of the basic advantages of clean coding. Reasons for clean coding -  • Reading clean code is easier - Every code is revisited after certain amount of time either by the same or different developer who created it. In both the cases, if the code is unclean, its difficult to understand and u...
