1. IDEA 1 OF 8

   Technology outruns institutions

   Azhar argues that technologies such as computing, renewable energy and biotechnology are improving at exponential rates.

   Meanwhile, laws, businesses and social norms change slowly, creating what he calls the exponential gap.

2. IDEA 2 OF 8

   Costs fall again and again

   Azhar explains how the cost of computing, solar power and gene sequencing has dropped dramatically over decades.

   Each fall opens up new uses. Cheaper tools make new businesses possible that were once too costly to try.

3. IDEA 3 OF 8

   Growth compounds quietly

   Azhar notes that exponential change looks slow at first, then suddenly overwhelming.

   People and institutions often fail to anticipate it. By the time the change is plain to see, it may already be too large to manage easily.

4. IDEA 4 OF 8

   Big platforms grow bigger

   Azhar argues that digital companies benefit from network effects and data, letting them dominate markets.

   Winners can take almost everything. The more users a platform has, the more useful it becomes, which draws in even more users.

5. IDEA 5 OF 8

   Some firms seem almost limitless

   Azhar describes unlimited companies that can keep growing without the usual limits of size.

   This challenges traditional rules about competition. Software and data let them reach huge numbers of customers without needing matching growth in staff and buildings.

6. IDEA 6 OF 8

   Work is changing

   Azhar discusses how platforms and automation are reshaping work, including the gig economy.

   Workers' protections have not kept up. Rules and safety nets built for steady, full-time jobs struggle to cover this new kind of work.

7. IDEA 7 OF 8

   Production may come home

   Azhar argues that technologies such as 3D printing and renewable energy may allow goods and power to be produced closer to where they are used.

   In his view, this could change how supply chains and cities are organised.

8. IDEA 8 OF 8

   Nations compete over technology

   Azhar describes growing rivalry between nations over technology and data.

   He calls for institutions that can adapt faster. In his view, old systems of rules are too slow for technology that changes this fast.
