At the start of December 2022, I came across some talk of the release of ChatGPT just a day after it became public. I immediately wanted to try it and signed up and got going. Since it was very new, I had no idea what to prompt, but I just finished working on some Python code for a class I was following. With just a single prompt, describing the problem I had just finished, ChatGPT wrote the entire code I was just working on for hours in a matter of seconds. I was perplexed.

Over the following 2 years I followed more programming courses, using different languages just as Java, R and Python. As I wanted to learn and understand the fundamentals, I always started on the code myself, but as I encountered problems or didn’t know where to start, I used ChatGPT which saved me hours of trial-and-error and searching online for answers. While the code it generated was often not perfect, by going back and forth describing the errors or problems I was experiences, most problems were fixed in a matter of minutes.

At the beginning of my programming experience 3 years ago I had an idea for a piece of software that I wanted to build myself, after many hours of encountering lots of problems and barely understanding where to start and how to progress I gave up. Recently I restarted this project, since now I have more programming experience, but especially feel way more confident I can reach my goal by leveraging the power of GenAI. The past years new GenAI tools that focus directly on programming have been released, with Cursor being one of these tools that seems especially fit for my needs. The development regarding programming and GenAI are incredible, and we will see what the future unfolds.

With the introduction of Bitcoin in 2009, the world experienced the first and currently biggest and most well known blockchain. While Bitcoin is mainly focused as a monetary payment network, blockchain as a technology is increasingly being used in multiple industries with different applications.  I personally follow developments with regards to blockchain and cryptocurrency for about 4 years now and the application of blockchain that intrigues me the most (after Bitcoin) is in supply chain management, especially after discovering the Dutch company ‘Open Food Chain’ which uses blockchain to make food supply chain more connected, transparent and sustainable.[1] This essay will therefore explore possible role blockchain can have in supply chains.

In short, blockchains are decentralized ledgers that store transaction in consecutive blocks (clusters). The transactions cannot be reversed, changed and are transparent. These characteristics are valuable in supply chain management since they allow for accurate tracking and traceability and current supply chain data is not always accurate, available or to be trusted.[2][3]

One of the biggest benefits of the implementation of blockchain in supply chains will be trust by consumers.[4] Due to the transparency and the traceability, supported by the security of the network, consumers in the future will be able to verify or have trusted third-partied verify the origins of their desired products. Transparency could allow consumers to know (‘trust’) that their products for example are ethical (no child labour involved), are the original product (reduced counterfeiting) and are safer (the entire supply chain is tracked).

While there are potential challenges such as high implementation costs and integration with the current systems and regulations,[5] I think in the future almost all supply chains will be built and tracked on blockchains because of consumer demand and pressure. As certain companies within an industry promote the transparency of their supply chains, this can result in a competitive edge that other companies will copy which in the end results in all companies following suit.
