I'm Harry Chang. I build safety systems for language models, take photographs on a camera with no screen, and argue for positions I'm not sure I believe in.
Now a freshman at NTU CSIE. I work across research, photography, debate, and the occasional film, whichever one the day needs, and write about what happens in between.
None of it is as separate as it looks. Every page here connects to another; if you'd rather see the whole shape at once, there's a graph for that.
