"The use of 4D in the product's name is a marketing term as the chip is still based on 3-D technology."

Lest anyone be led to believe it's a warp drive?

Also reacted on that. "What's better than 3D? 4D!" :)

Reminds me of the alleged story about Xbox naming schemes. IIRC, Xbox was introduced when Playstation 2 was in stores. Then came the Playstation 3, but you can't sell an Xbox 2, since 2 is lower than 3 and thus must be worse, right? And Xbox 3 or 4 wouldn't make sense since there wasn't an Xbox 2.

So they named it Xbox 360 to bypass that problem.

But then what, Xbox 720? Xbox 361? Of course a new naming scheme had to be devised -> Xbox One. Then Xbox One X, and now Xbox Series X (and S).

Kinda funny how that seemingly small thing escalated to what seems like a series (ha) of workarounds to that initial problem.

They should have included an "Xbox 2" plush toy with the Xbox 3.

As someone who has worked for a NAND based flash memory manufacturer, time is definitely a relevant dimension.

Our whole company was hinged on a patent for a manufacturing technique to make either the source or drain leads a little more pointy so things could run faster and be more reliable with less power.
