Folks, I think we're on to something here...

First we invented LLMs and we were like, "Programming is so dead. Just talk to the AI."

But that didn't really work without context. So we gave them context, which is basically state.

Now they needed to actually do stuff, so we gave them tools and functions, which are basically APIs and... functions!

Then we invented MCP, which is basically a standard interface for connecting all that stuff together.

After that we were like, "Yeah, these things should just keep running," so we invented agents, which are basically LLMs in a loop.

And now we have JEV, which is basically giving the LLM IF / THEN / ELSE.

So after spending years explaining that AI will replace programming, we have gradually added:

state
APIs
functions
interfaces
loops
conditionals

At this rate, the next AI breakthrough will be exception handling. Then types. Then unit tests.

And eventually someone will have the revolutionary idea of writing a precise, reusable set of instructions for the computer in advance.

We'll call it PromptScript™.

Full circle :)
Note from Claude Sonnet 5

A long text tweet by @tunc_y tracing how LLM tooling has gradually re-added state, APIs, functions, interfaces, loops and conditionals, and predicting exception handling, types and unit tests next. Posted as tongue-in-cheek commentary on LLMs re-inventing programming.

My personal "AI holy S\*\*t moments" list... Starts with... \*\*\* Racter (1986 - Commodore Amiga) "The computer can talk! The computer can freaking talk!" NOTE: At this point, I started trying to code chatbots on the amiga... Followed by some Visual Basic experiments on the PC, quickly realising pattern matching didn't work and that I needed to go for some statistical model that picked the most likely word. And for the knowledge side, I was thinking about using some sort of graph that linked concepts and words... However I was absolute sh\*\*t at maths and never managed to crack these problems :) \*\*\* GPT 2 (2019) "Wow! Statistical next word prediction really works!" \*\*\* ChatGPT 3 and 3.5 (2022) "What?! I am talking to the freaking computer and it is talking back!" \*\*\* ChatGPT 4o (2024) "That's it! AGI is here!" (First deep chats with AI - super impressive) \*\*\* GPT o1 (Dec. 2024) "OMG! There is no plateau!" IMPORTANT NOTE 1: SOMEWHERE AROUND HERE THE AI STARTED BECOMING REALLY USEFUL FOR CODING (although with several mistakes you had to fix) AS WELL AS OTHER WORK (planning, summarising, reading startup pitch decks, preparing them etc) \*\*\* GPT o3 (Apr. 2025) "These clankers are getting smarter than me!" (I was super impressed with o3's go getter attitude... I would ask it some startup question and it would be like "now find 5 people, do cold calls and tell them xyz, get your first customer, reach 1000 MRR followed by 20% margin") IMPORTANT NOTE 2: SOMEWHERE AROUND HERE THE AI STOPPED MAKING MISTAKES WHILE CODING - AT LEAST AT MY LEVEL. \*\*\* Opus 4.6 (Feb. 2026) "Cool, I don't even need to look at the code anymore!" IMPORTANT NOTE 3: SOMEWHERE AROUND HERE THE AI STARTED BECOMING CRAZY GOOD AT MOST STUFF RELATED TO CODING, WORK, DESIGN, PLANNING etc... \*\*\* Fable 5 (Jun. 2026) "OMFG! This thing can code full 3D games from start to end!" (but is freakingly expensive) \*\*\* GPT 5.6 SOL (Jul. 2026) "Wow this is as good as Fable for a reasonable price!" \*\*\* GPT 6 Astra (Sep. 2026) "\<insert curses used when amazed here> it can use blender and make game assets then put them together and make flawless games!" (ok except for taste, level design and fine tuning difficulty etc) I probably forgot a lot of stuff in between...No matter what, it has been an absolutely wonderful journey and notice how things have accelerated beyond belief! What a time to be alive! Note: I intentionally omitted audio/video/image gen as well as open source... There have been several "omfg" moments there as well...
