If you thought we'd never see a repeat of the GFC or even the dotcom bubble, think again...  So far financial markets have proved remarkably resilient to the geopolitical shocks and uncertainty brought about by Trump 2.0, but economists are warning that this could be largely thanks to an AI bubble that is artificially propping up the US economy.  Geraldine Doogue and Hamish Macdonald discuss the growing fears of what happens if and when this bubble bursts and how Australia is particularly exposed to a downturn through our superannuation system.  Then Geraldine sits down with the acclaimed Irish economist and author David McWilliams to put this moment in historical perspective and get his frank assessment of what comes next.    Get in touch: We'd love to hear from you!
