speaking balance: gold is the hosts, purple is the guest (3 minute bins)
Jordy pushes back on John's ranking of Fed chairs, rejecting the premise that shutting down the global economy during COVID was not a major crisis.
Hardest push from the hosts ▶ 18:24 John counters economic crisis comparisonJohn refuses Jordy's framing by distinguishing rate-setting from stimulus, pointing to strong 2019 consumer balance sheets and lack of shadow banking collapse compared to Bernanke's era.
Biggest teaching moment ▶ 19:36 Tyler reframes absence of catastrophe as competenceTyler educates the group by reframing Powell's tenure, arguing that the absence of a catastrophic collapse during COVID is evidence of effective central banking rather than an easy environment.
The host holds their own ▶ 10:20 Deep dive into semiconductor physics and memory limitsJohn displays strong technical expertise detailing SRAM scaling stagnation across process nodes and the compute-versus-memory trade-offs inherent to wafer-scale engines.
