Often but not always. For most newer FPGAs, routing is the main source of delay on the critical path, not logic. So if the synthesis tool lowers the logic depth, but does so in a way that increases the distance the signal must travel on the chip, it likely won't help FMax.

This can be caused by increased logic usage, if the synthesis tool must create significantly more LUTs to reduce the critical path. This may make it harder to place the logic on the critical path close together, increasing the routing delay.

Additionally, if the synthesis tool replaces something with a dedicated routing path (most FPGAs have dedicated routing for carries, some may have dedicated routing for local connections in a CLB or between CLBs). These dedicated routing connections usually have a lower delay than the general purpose routing network, potentially increasing delay

The figures they have listed look promising though, they're lower or comparable to the commercial tools in terms of resource usage, with lower or comparable logic depths. They do however not have support for things like carry chains, which may potentially make some things like adders slower than the other tools.

Henrik has a blog post about a SAR radar he made from a couple years ago that goes into a bit more detail about how it works https://hforsten.com/synthetic-aperture-radar-imaging.html

With price increases over the last couple of years from inflation, retailers have shown they are more than capable of doing so already. So yes

That is unlikely to work. Centrifugal separation works when the fluid you're trying to separate is a suspension of either solids or multiple fluids that do not mix (such as oil or another fat and water). Blood is a suspension of several types of several things (red and white blood cells, platelets, minor amounts of other stuff) in plasma, so you can separate each of those components out with a centrifuge. Soda, unless it contains something like fruit pulp or dairy, is generally not a suspension and therefore will not be separated by a centrifuge

The article only briefly mentions crypto and is instead about products like Paypal, Cashapp, Venmo, and the like.

Clones of the 8051 are pretty popular in that scenario, I know for sure at least one mouse manufacturer uses them and probably a ton more
