Fri-yay indeed. We sigh, as humans spool up to take a break, while the semi-sentient machines continue writing their poetry in their air-conditioned underground data-center homes. In my column this week, I spent a bit of time thinking about the times that robots have had an impact on my life. That time I ran a chatbot company talking with people about death. That time I felt a connection with a game character. And that time I tried to imagine what it would be like to be a sentient AI knowing it was about to get shut off.

It’s a series of thought experiments I’ve been playing with for a long time, and the idea was reawakened by reading Becky Chambers’ excellent Wayfarers series. The second installment goes into great depth about what happens when an AI is rebooted — will she come back with all her memories intact? Or does something change when you go back to your default software? Well worth a read, if you want to be a philoso-fish, swimming in the philoso-sea.Over the past couple of weeks, the internet went positively bonkers over the possibility of superconductors operating without being chilled to near absolute zero, after a team of researchers in South Korea claimed they had something cooked up in the lab that worked. The problem, in part, was that they claimed to have used a material (lead apatite) that not only isn’t a known superconductor, but also isn’t, in fact, conductive at all. YHBT, YHL, HAND, as they used to say in the early days of the internet.

Still, for the briefest of glimpses, on TC+, Tim explored the potential of such a development and the vast-ranging impacts it would have on, well, everything we know about electricity, electronics, and much more. Of course, it seems it may not have been true, and reminded us of the iffy claims made by another company back in March, also involving the elusive room-temp superconductivity.

Alas, ’twas not to be this time either, but the hunt continues.Less confusion, more fusion: Tim is basically single-handedly carrying this entire section this week — well done, squire — reporting how scientists repeat a breakthrough fusion experiment, netting more power than before, bringing us one baby step closer to usable fusion power.

If you love yourself some sustainability, get your behind (and the rest of you, please. If you turn up at the doors, just a pair of levitating buttocks, we have achieved some sort of superconduction, but you’ll have made an ass of yourself, and security will probably turn you away) to TechCrunch Disrupt, where we have a whole Sustainability Stage planned
