LLM Inevitabilism

In the 90s a friend told me about the internet. And that he knows someone who is in a university and has access to it and can show us. An hour later, we were sitting in front of a computer in that university and watched his friend surfing the web. Clicking on links, receiving pages of text. Faster than one could read. In a nice layout. Even with images. And links to other pages. We were shocked. No printing, no shipping, no waiting. This was the future. It was inevitable.

Yesterday I wanted to rewrite a program to use a large library that would have required me to dive deep down into the documentation or read its code to tackle my use case. As a first try, I just copy+pasted the whole library and my whole program into GPT 4.1 and told it to rewrite it using the library. It succeeded at the first attempt. The rewrite itself was small enough that I could read all code changes in 15 minutes and make a few stylistic changes. Done. Hours of time saved. This is the future. It is inevitable.

PS: Most replies seem to compare my experience to experiences that the responders have with agentic coding, where the developer is iteratively changing the code by chatting with an LLM. I am not doing that. I use a "One prompt one file. No code edits." approach, which I describe here:

Compare these positive introductory experiences with two technologies that were pushed extremely hard by commercial interests in the past decade: crypto/web3 and VR/metaverse.

Neither was ever able to offer this kind of instant usefulness. With crypto, it’s still the case that you create a wallet and then… there’s nothing to do on the platform. You’re expected to send real money to someone so they’ll give you some of the funny money that lets you play the game. (At this point, a lot of people reasonably start thinking of pyramid schemes and multi-level marketing which have the same kind of joining experience.)

With the “metaverse”, you clear out a space around you, strap a heavy thing on your head, and shut yourself into an artificial environment. After the first oohs and aahs, you enter a VR chat room… And realize the thing on your head adds absolutely nothing to the interaction.

Every single HN post on AI or crypto I see this argument and it’s exhausting.

When Eliza was first built it was seen a toy. It took many more decades for LLMs to appear.

My favourite example is prime numbers: a bunch of ancient nerds messing around with numbers that today, thousands of years later, allow us to securely buy anything and everything without leaving our homes or opening our mouths.

You can’t dismiss a technology or discovery just because it’s not useful on an arbitrary timescale. You can dismiss it for other reasons, just not this reason.

Blockchain and related technologies have advanced the state of the art in various areas of computer science and mathematics research (zero knowledge proofs, consensus, smart contracts, etc.). To allege this work will bear no fruit is quite a claim.
