I found this story fascinating:

Apparently, there was a 'bug" (or rather technically undefined area) in the original bitcoin code that would produce ANOTHER 21 mil btc starting in the year 256 from the get-go.
The "bug" was eradicated in BIP-42, which was done post-Satoshi.
Without BIP-42, rewards of 50BTC would restart in 256 years, then halvings would continue again (from 50btc/reward to down).

A bit of 'conspiracy' theory on my side, but how do we know if this was not the Satoshi's intent?
I keep reading about 4 mil 'lost" already in just 14 years.
What if Satoshi surmised that this loss in 256 years (with issuance stopping by year 2140) would bring available bitcoin numbers too low and actually designed the "bug" to revitalize bitcoin about a century after. Interesting, but would not affect things in our lifespan, perhaps.
