Yes. Because it's not a simulacrum, it's a greatly simplified model. That it works at all suggests you've discovered at least a few of the important principles that let the vastly more complicated original work.

Also, you can poke at the model, see what improves it, what breaks it, plot receptive fields, all those things that are messy, difficult or unappreciated in an actual brain.

How's this, in the last 10 years, what if instead you didn't have 4G / LTE etc, instead you just still had "inefficient EDGE" BUT unlimited data, all month long, endlessly?

You mean... what if the cellphone carriers didn't take advantage of any of the advances in technology that had happened, and just gave us the same shit sandwich they were giving us 11 years ago?

I'd be pretty pissed about that completely different situation too. I'd say to them "Look, why not use the new spectrum the government is opening up for you, use something really efficient like LTE, and offer us more bandwidth for the same cost given we're paying you the same amount of money now as we were when you were still upgrading your network?"

Technology has improved. You'd expect that to result in actual improvements beyond being able to see a web page render more quickly on your mobile. We know capacity has improved, so why can't we access it?

I'm finding it fairly amusing that Windows 3.x actually looks quite fresh and, ugly pre-anti-aliasing font aside, fairly modern. Which is odd because at the time, as a user of AmigaOS 2.04 at home, I thought it looked clumsy and ugly (and everyone else started to agree about the look of Windows 3.x when Windows 95 came out.)

There's a lot of flatness to the Windows 3.x UI, which is something that's in vogue again.

Gigabit LTE means that you'll be able to use up your entire high speed data quota in less than a minute, unless the carriers finally update their data pricing models.

How is it that we've ended up with $10 for 10Gb or less of data now for about ten years? In the meantime, we've gone from inefficient EDGE to unbelievably efficient LTE, with HSPA+ available now for, what, the last five years on most GSM family networks?

Yet the data prices haven't budged. The carriers have more bandwidth than ever, more efficient ways of using it than ever, but they still think they're running ancient EDGE or cdma2000 networks.

On a positive note, this is more bandwidth than most people's cable modems. I wonder if the cable industry will catch up.

From various observations (and the theory of general relativity) we're pretty sure gravity propagates at the speed of light. You find gravity everywhere because it's already there, the same way that walking from a dark room into sunlight doesn't imply that light travels from the sun to your eyeballs instantaneously.

If the sun were suddenly dematerialized you would continue to see sunlight for another eight minutes. We are also fairly sure that the Earth would continue in it's orbit as if nothing had happened for eight minutes, until the gravitational effects of the disappearing sun had time to propagate.

Since Newton we've made a variety of observations that we're fairly sure imply gravity propagates at a finite speed. If that's true, it's very difficult to construct a theory that doesn't include waves. Realistic MOND theories (i.e. more than just "GR is wrong.") include gravity waves, although they might disagree with relativity about how easy they are to detect.

There's no way we're going to focus gravity waves any time soon. But (I think) you could build a gravity wave interferometer. LIGO effectively IS sort of a gravity wave interferometer right now, with the baseline between the two sites giving it the ability to determine the rough direction to the sources. If you wanted to build up an image you'd need a lot of LIGOs, but it would be possible. And awesome.
