Is your work future-proof? On this week's show, we talk about the decentralized future of manufacturing in a long-awaited (by us) episode featuring 3D printing technology and the questions of a world without human labor. We also discuss the evolution of Bitcoin Core, particularly with BIP 47's proposal for payment codes as a solution for user privacy.

We're joined this week by Bitcoin master Andreas Antonopoulos to discuss his work in multisignature security with [Third Key Solutions](https://www.thirdkey.solutions/), his recent book *Mastering Bitcoin*, his thoughts on Bitcoin Core development and the block size debate, and why he thinks decentralization is so important for justice.
