Yes.  If you look at the specs page, the high-end video cards (the Radeon Pro W5700X, W6800X, W6900X and W6800X Duo) each include four TB3 ports and one HDMI port.

Then there are two more ports on an I/O card and two built-in ports mounted in the top of the case.

There are quite a lot of people who want a small phone.  I read posts by them whenever the subject comes up.  They liked the 3.5" screen from the iPhone 4 and often complain that everything sold today is too big.  The SE2, being the smallest screen currently sold (at 4.7") is what they settle on.  When asked, they think the 5.4" screen of the 12 mini is too large.

I suspect these people will definitely be interested in an SE3.  Especially if it retains the 4.7" screen and gets a modern processor inside.  The other people who will be interested are those who don't want to spend $700 on a 13 mini - a $400 SE3 is far easier on the budget.  There are also some who really prefer Touch ID, but I have no idea if these people like it enough to be the deciding factor on a new phone.

Are there enough people in these categories (small screen, Touch ID and/or low budget) to make an SE3 profitable?  I don't know, but I would like to think that Apple's marketing people have done the research to come to an intelligent decision.

This looks like an incremental change to what they're already shipping.

For example, the older MacBook Airs, with aluminum bezels around the screen, have a camera-in-use light that is almost completely invisible when it is not lit.  The LED is behind a group of microscopic perforations in the aluminum.

I've also seen something like this on some HP laptops, to make the logo light up on the back of the display, without showing anything that looks like a lens when turned off.

The idea of aligning micro-LEDs with these pinholes in order to provide a more robust kind of invisible display has never been done before (and hence is patent-worthy), but it still strikes me as an incremental upgrade to tech that's been around for quite a while.

I don't think we'll ever see this on a laptop - Apple seems much more keen on simply using edge-to-edge OLED displays (with a notch, where necessary), and would therefore just use that display for the output.  But it might make sense on a device that doesn't normally have a display, like (as their example showed) an iPad pencil-like device.

Let's just hope they don't decide to start replacing keyboards with these flat-haptic displays.  Apple's keyboards are flat enough as it is.  Going completely flat and immobile would be a disaster for anyone who knows how to touch-type.

Not really possible.  As far as cables are concerned, there is no "version" and no ID chip.  There is simply the maximum amount of bandwidth that the cable can carry with a clean signal:

The important thing is that the amount of bandwidth you require depends on what features your devices are using (resolution, color depth, encoding, etc.).  Even if your devices are HDMI 2.1 compliant, if your particular combination of devices only requires (for example) 8 Gbit/s, then you can use cheap category 2 ("high speed") cables.  You don't need a category 3 cable unless your devices require more than 18 Gbit/s.

The real problem is that if you're not a very technical person, you probably don't know how much bandwidth your devices require.  So you'll probably take a look at the version number and pick your cable based on that (e.g. get a category 3 cable if the devices are HDMI 2.1), but this may easily result in paying for more bandwidth than you actually require.

It's a nice looking device, but I wouldn't trust any space heater with "smart" controls.

Nearly all space heaters you buy include warnings not to run them unattended.  The ones in my home are unplugged when not in use.  Despite all of the latest safety features, I think the risk of fire, should something fail, is always going to be too high for me to leave a device plugged in 24x7, controllable by a remote app.

I also don't leave toasters or coffee makers or other small appliances with heaters plugged in when they're not in use.  They sometimes fail, and when they do, fires sometimes start.  There are news articles every year about fires that start because of faulty appliances or space heaters.  I really don't want to become the next such statistic.

BTW, the article says that the 2000W unit isn't available yet.  I'm not surprised.  1500W is about the maximum you will ever find on a device designed to connect to a 15A circuit (15A * 120V = 1800W, and manufacturers always leave a margin, because there are always other devices plugged in to the same circuit).

A 2000W unit will draw a minimum of 16.7A on a 120V circuit.  We can expect that if they release such a device, it will require a 20A and/or a 240V circuit (much like room air conditioner units typically require).  For most houses, this will mean an electrician will need to run a new circuit from the service panel.
