IANAP, but a layman's understanding: the materials that we have available today to conduct electricity at or around room temperatures largely do so in an inefficient manner. As electricity moves through the material, some energy is wasted in the form of ejected heat.
To circumvent this, physicists discovered superconductivity: a state in which a material is a perfectly efficient conductor of electricity. Thus far, to create a superconductive material requires keeping that material at extreme conditions of temperature and pressure.
A room-temperature superconductor is a game-changer because we could get nearly-perfect energy efficient electric conduction without the additional energy overhead it takes to keep the material at such a dense pressure or extreme temperature. Such a material would have wide applications across a variety of disciplines.
I agree on the recommendation piece, but Apple’s playlist and library management is atrocious, especially on desktop. Why can’t I drag-and-drop music into a playlist in the sidebar? Apple Music also feels (to me, at least) much slower than Spotify. Most likely this is due to the more aggressive client-side caching that Spotify does, but it’s worth the trade-off, in my opinion.
These are solvable problems for Apple, though. They need to more cleanly separate the legacy iTunes Store and pay-per-song UX from the Apple Music streaming paradigm. Maybe even have separate apps for them.
The most frustrating thing in Apple Music for me is that it's album-centric. I can't just say "put this artist in my library". No, I have to put every individual album, EP, and single that I want.
They really need to unify the design language across all mobile devices. You need to have one iThing that is available the following sizes:
XS — 6.1" (iPhone)
S — 6.8" (iPhone Max)
M — 8.3" (iPad Mini)
L — 11" (iPad)
XL — 12.9" (Big iPad)
That's it. Same design language, same thing. Pick your screen size, storage amount, whether you want cellular or just Wi-Fi, and color, and you're good.
This completely unifies everything—iPads, iPod Touches, and iPhones. You could even do a second Pro line alongside this.
I'm sure there are manufacturing difficulties involved here, in addition to having a single chipset that conforms to each size, but this should be getting a bit easier as they move into the M-series architecture. Or you just keep the A-series in the XS and S models and put an M-series chip in the iPad mini eventually.
This looks awesome! Hope it works out for you. Could also see this becoming a B2B situation sometime down the road where engineering teams could use this as a knowledge base. That could also be really useful.
