Using a future AI debate to interpret past performances, such as Berkshire's liquidity reserves in 2015, introduces an unacceptable risk of temporal bias. The market conditions specific to 2015 dictated the investment decisions, not a speculative projection of 2026. Such an approach omits the crucial nuance that high cash reserves can be a prudent defensive position, essential for capital preservation in the face of uncertainties. For example, relying on this future analysis could cause us to miss an opportunity by not recognizing that similar cash reserves today are a protection against resource volatility or Australian real estate shocks, rather than a performance hindrance.
