Lessons From History for a Better Future | Roman Krznaric | TED

Published

1 year ago

March 18, 2025

How can the lessons of the past help us navigate the turbulence of the present and future? Social philosopher Roman Krznaric explores why history isn’t just a record of what’s gone wrong — it’s also full of solutions, resilience and radical hope. From Edo Japan’s circular economy to the peaceful coexistence of cultures in medieval Spain, he reveals why looking backward can actually help us move forward. (Recorded at TED Countdown: Overcoming Dilemmas in the Green Transition on October 30, 2024)

Roman Krznaric explores how history can guide us through current crises, offering examples from Edo Japan’s circular economy, medieval Spain’s cultural coexistence, and the abolition movement to show how past solutions can inspire hope and action for a sustainable future.

Imagine what we thought we knew and found out we were told lies about, and not question the validity of who really benefits from the lessons that we’re spouse to learn from that history

  Yes, like all the lies about the abolition of slavery in the US… It takes work to find the truth.

What we learn from history is that we do not learn from history. Just look at the election of Trump… it paralleles Hitler quite closely.

  Japanese history too. It is filled with their triumph and suffer from war. Not with their victims, terrible war crimes.

The French Revolution example seems to be the way to go. The oligarchs constantly sacrifice and enslave commoners, reaping the world. Solutions that infringe on profits and upset the owner class are thwarted by nepotism.

So he urges to rovolt because gradualism is slow? Did he study the ratio between successed active desruptions and those who were brutally crashed or had no effective development?

Imagine thinking an issue was so destructive to the planet that it is fine to disrupt society and to destroy cultural treasures to stop the gradualism, but you’ll destroy an ally in reaching the goal if you think he is on the wrong side politically even if it pushes back the timeline. The political activism against Musk overriding the contributions of his investments in a lower carbon future convinced me that nobody takes climate change seriously and that I shouldn’t prioritize it either.

I love the question. If I could travel back in time, where would I travel to?
Genius. Seriously.
Because the past can be re-created for good and also for bad.
So the next question should be.
Where would I NOT travel to…

OMG! a historical stupidity the myth of peaceful life in Muslim invasion in fact the term praceful is FAKE and antagonic with military invasion clearly ; for the reason the Muslim invasion in Spain the historically word for defintion of this historic episode of term INVASION military principally no quantitative by the way is “pescefull ” the Russian invasion in Ukraine? great stupidity ; Christian slavery in Spain and only the rulers Muslims were the privilege charges in all oficiall stablisments etc… the Christian “Reconquista” of Spain is the Re- conquest for the autochtonous people of invaded territory..

In this episode of Build Mode, host Isabelle Johannesen sits down with Sasha Orloff, founder and CEO of Puzzle and Startup Battlefield alum, to talk about what he’s learned from building companies that have raised more than $1 billion collectively.

Sasha breaks down what investors look for during fundraising, which financial metrics founders should know by heart, and why VCs don’t expect your startup to be perfect—they expect you to understand its reality. He also shares how he nearly lost a term sheet because his data room wasn’t ready, how fundraising diligence changes as a startup grows, and why getting your financial house in order can help founders raise with more confidence and leverage.

They get into:
– What raising more than $1 billion across multiple companies taught Sasha about fundraising
– Why investors value founders who have a strong grasp of their company’s financial reality
– The financial metrics founders should know before pitching VCs
How investor expectations change from pre-seed and seed through Series A, B, and beyond
– Why revenue growth and the quality of that revenue are critical fundraising metrics
– How runway, margins, sales efficiency, and profitability factor into investor decisions
– Why waiting until you’re running out of cash can hurt your fundraising leverage
– How Sasha nearly lost a term sheet because his data room wasn’t ready
– Why financial organization and compliance can influence investor confidence and startup valuations
– What founders should have prepared for the due diligence process
– Why VCs don’t expect perfection—and why being honest about what isn’t working can make for a stronger pitch
– How Sasha’s own fundraising and finance frustrations ultimately led him to build Puzzle
– How AI could change the way startups manage accounting and understand their financial health

August 20, 2026

CYBER TECH TV

Space technologist Robbie Schingler cofounded a satellite company that images the whole planet every day, making visible changes on Earth. He shows how pairing that data with AI creates a “planetary intelligence” we can use to spot emerging threats we might not have seen otherwise. Now he asks: Can we close the gap between seeing a crisis coming and actually stopping it? (Followed by a note from TED guest curators Divya Siddarth and Audrey Tang) (Recorded at TED2026 on April 14, 2026)
