What Hacker News says
5 sources1.) Not something I did. I only worked on the software.
4.) Contracted because I wrote the Open Source libraries it uses. I created https://github.com/pion/webrtc and https://webrtcforthecurious.com the company reached out to me because https://github.com/sepfy/libpeer didn't work with Pion. Turned out to be a libpeer bug (which I fixed)
> were you really hooked
I have been doing hardware + WebRTC with lots of different projects since then. https://www.youtube.com/@seandubois86 unpaid, that's my proof at least :)
> Hooked on the technology stack.
Yes I enjoy doing WebRTC + C https://github.com/awslabs/amazon-kinesis-video-streams-webr... (one of original authors) so I enjoy the tech a lot.
> Hooked talking to Santa
I enjoy the unexpected behaviors of Voice AI at this moment in time. In the video I asked Santa about pi, and it responded in

a way I didn't expect. I find it absurd/entertaining.
> Do you have kids that you built it for
Yes. I have a few toys/personalities that I built for my kid. They make up funny scenarios/personalities and I change the prompt and put it in a different toy. It's fun.

The first time I talked with AI santa and it responded with a joke I was HOOKED. The fun/nonsense doesn't click until you try it yourself. What's even more exciting is you can build it yourself:
libpeer: https://github.com/sepfy/libpeer
pion: https://github.com/pion/webrtc
Then go do all your fun logic in your Pion server. Connect to any Voice AI provider, or roll your own via Open Source. Anything is possible.
If you have questions or hit any roadblocks I would love to help you. I have lots of hardware snippets on my GitHub: https://github.com/sean-der.

In Hardware AI Toy I worked on is available in storesI am so happy that WebRTC has so many implementations. Every developer thinks differently, it's good to have a implementation that matches your mindset.
