Why the decisions we make today will shape humanity for centuries

Executive overview

We are biologically wired to prioritise the short term — survival instincts that served us well against predators now distort how leaders, companies, and governments make decisions. The future is a verb, not a noun: something we actively do through every choice, not a destination that washes over us.

Futurist Ari Wallach argues that the current decade is one of the most consequential in human history. Decisions made now — on AI, climate, biotech, governance — will shape the species for two to three hundred years. The antidote is "futuring": deliberately practising long-term thinking as a skill.

The core insight: short-termism isn't a bug in human cognition — it's a survival feature that now needs deliberate override.

Why our brains default to short-term thinking

• The brain treats our future self like a stranger: fMRI research shows the same neural region fires for "me in 10 years" as for a distant celebrity.
• Simple interventions close the gap — writing a letter to your future self or viewing an aged photo of yourself shifts how the brain represents that future person.
• Negativity bias evolved to spot threats; it now manifests as near-universal dystopian storytelling in culture, which reinforces short-term decision-making.
• Hunter-gatherer wiring for immediate survival is unchanged; civilisation requires actively overriding it.

What futurists actually do

• Track megatrends (Long Path Labs monitors 21, from climate to psychology to spirituality) that operate on decade-plus timescales.
• Build four scenarios — not best/worst case — then ask: what has to be true for each to materialise?
• Backcast from desired outcomes rather than forecast from current trajectories.
• Separate signals from noise, then ask: which future do we actually want?

Why business leaders struggle to think long-term

• Corporate incentives (quarterly earnings, short tenure) structurally reward short-termism at the individual level.
• The longest-running companies on earth — many Japanese firms over 1,000 years old — operate as family businesses where the current leadership sees itself as stewards for future incumbents.
• Post-pandemic, leaders feel pressure to stay silent on big social questions; Wallach argues they must instead reconnect with the moral imperative of their business beyond shareholder returns.
• Future generations are the most marginalised stakeholder: they don't vote, have no proxy, and no seat at the table.

The AI and Oppenheimer parallel

• AI is currently being optimised for near-term business interests within a small group of owners — not for planetary flourishing.
• Building AI to help sell ads or find cheaper flights is a waste of its potential; building it to solve food, housing, and education at scale is what Wallach advocates.
• A public AI infrastructure — a "Manhattan Project for flourishing futures" — is needed but not happening.
• The media covers AI governance like horse-race politics (board seats, investor returns) rather than as the civilisational question it is.
• Oppenheimer's lesson: concentrated power over transformative technology demands collective accountability, not just market competition.

The "Future Design" method and temporal agents

• In Yubari, Japan, a third of participants in civic planning sessions don ceremonial robes and speak as citizens of 2060 — the tenor of the room shifts entirely.
• The goal isn't for future generations to "win" over the present; it's to make their needs part of the dialogue.
• CEOs can act as temporal incursion agents: people who hold the full timeline in view and ask what's in the interest of both present and future stakeholders.
• Even small decisions — which LLM to use, whether to scrape certain data to train models — compound over centuries.

Three practices for futuring

1. Ask: "Am I being a great ancestor?" — not in a grand gesture sense, but in how you show up today. Would your children model their behaviour on what you did?
2. Write a letter to your future self. The research benefit comes from the act of writing, not receiving. It changes how you conceive of your role in shaping the future.
3. Become death-aware, not death-anxious. Ernest Becker's Denial of Death argues that mortality fear drives short-termism. Accepting finitude opens the aperture: your actions are nested in a larger framework than your own lifespan, which paradoxically makes long-term thinking easier and less stressful.
