Also, if the talk is being recorded then explain it (briefly) anyway. The (potentially larger) later viewing audience may well include people who don’t know yet, and can no longer put their hands up. (Surveying audience to guage detail required is good though.)

This. On the Amstrad CPC even the system supplied disc copy tool would check what referenced unreadable sectors and declare a successful copy if the only unreadable sectors were unreferenced ones. If you can do that, maybe upload with note “99% read”. Better than nothing.

I’m not sensing Uncanny Valley from the still photos in that article. Most of them seem to me clearly on the “sculpture” side of the Valley. Generally I feel it more about video / movement rather than stills. Modern tech gets closer to crossing the Valley entirely.

Replying to @minxdragon

Random morning thought: possibly non-binary gender presentation is an Uncanny Valley for people whose experience is strictly cis-gendered “never thought about it before to be honest”. So maybe Uncanny Valley is easier to trigger in stills by being less stereotypically gendered?

I appreciate your point, but I didn’t think the point was to “make light” of the horror of the past. To me it seemed an attempt to keep people’s brains functioning to realise “oh no”, “are we the baddies?” about modern tech. 1/2 #lca2019

“Some of the past was horrible, feel the horror” risks people going away missing the connection to the present. And FWIW, the approach chosen got shared a lot, making more people think about the past and the future. But thanks for your important point. 2/2 #lca2019

Replying to @minxdragon

My thought was that adding something else some people perceived as “not quite right” would trigger Uncanny Valley even in stills. Eg agender presentation. (I agree movement triggers UV more easily, including for me.) Do you have a link to your paper? I’d like to read it.
