      This is obviously a mistake as it is sufficient to put the address (or its hash value) on the chain, the data (of any size) being stored on something like IPFS.

    3. There are inherent affordances and limitations to the technology that make some things possible and other things more likely. At the same time, there are complex individual and societal forces that impact how it develops, especially the power structures that develop alongside a given technology.

      getting at the definition of technology.

    4. but they are instead examining how it developed in a give context.

    5. We saw this happen with Microsoft. It started out with a big vision: How do we get a PC on every desk and in every home? It was profoundly democratizing.

      This is not true. Closed and proprietary was baked into microsofts DNA since Day.
