Agree. AI's productivity promise is a major problem for the banks and indebted governments. But, if the 1990s are any guide, this problem will ultimately end up back in the lap of savers and holders of the currency.
When you look back to the last major tech advancement -- the internet -- you see prices coming down in the first half of the 1990s. Again, big problem for the banks and government. Greenspan starts priming the pump in the mid-90s, changed the CPI definition in 1996 to mask his expansion of the money supply -- leading to the bubble and crash.
In other words, paraphrasing
@Saifedean Ammous, "a slow drain of monetary value over time transfers the wealth of its holders to those who can produce the medium at low cost." The government will need to offset the productivity gain.
