In 2017 I worked tirelessly with my colleagues to implement and replicate the first transformer paper. Yesterday I left Opus 4.8 to go do some architecture research, with GPU access. It replicated and trained a credible baseline. It implemented some ideas I'd been thinking about, and wrote custom CUDA kernels for them. It read and summarised dozens of related papers. It has since run dozens of experiments, with minim…

> The prospect of recursive self improvement feels more to real to me all of sudden

The Skynet Funding Bill is passed. The system goes on-line August 4th, 1997. Human decisions are removed from strategic defense. Skynet begins to learn at a geometric rate. It becomes self-aware at 2:14 a.m. Eastern time, August 29th. In a panic, they try to pull the plug. Skynet fights back.

My furnace went out during the 2025 holiday and I couldn't get an appointment with a repair person for 2 days. It was getting very cold in my house so I went into my attic and made several videos of the furnace attempting to start and gave it to gemini. It diagnosed the issue immediately and had me spin one of the components (a small exhaust fan) while the furnace tried to fire. It came on immediately. I had to do th…

Another home improvement example for me: my washing machine stopped spinning. I looked online for the machine manual but couldn't find it with basic search. I had ChatGPT Pro search for the repair manual (for service technicians) and help me troubleshoot my problem. It found a PDF of the manual somewhere and pointed me in the right direction to start diagnosing. Between reading the manual and prompting for extra help, I was able to pinpoint the area of the issue, and found that a belt had come off from a wobbly pulley wheel. Tightened up the wheel, put the belt back on and fixed it (at least for now).

Same happened to me. I only had to ask the service where to tap exactly.

I guess I've had several of those moments over the last year and a half. But a recent one was that I was working with Claude to create a spiking neural net MNIST classifier in an FPGA for a demo. Claude took it from concept to PyTorch, to training (training a Spiking neural net isn't necessarily straightforward - that's a whole post in itself, but Claude came up with a working solution), and then to implementation in…

Very cool. Anything publicly available?
