This is an absolutely terrible article, it seems the author just quickly threw together a list of alternative computing technologies and added a clickbaity title. Fluidics as a post Moore's law computing technology is laughable. The maximum possible processing speeds are somewhere in the 10s of KHz. In addition, fluidics does not scale down well. Slime molds are purely a gimmick.
However, fluidics was/still is a practical technology for niche applications. Fluidic non-moving part logic devices have been used for for factory process control and integrated pneumatic controllers for aerospace for decades now. Fluidics can be very robust and reliable. In the time period of the 1960s-1970s fluidics was more reliable than similar electrical and electromechanical systems. One thing that still makes fluidics attractive today is its robustness in environments where transistors don't work. Fluidics can with stand high temperatures, high shocks, high radiation, high magnetic fields, etc. As long as the shape of the channel remains intact, fluidics still works. Fluidics has been demonstrated to work inside jet engines, nuclear reactors, and molten steel.
Because of fluidics inherent EMP resistance, fluidics has been considered for use in anti-ballistic missile guidance systems[0].
One interesting current day application of fluidics is kosher sound amplification[1]. Orthodox Judaism prohibits electronic sound amplification on the sabbath because it constitutes work. Using a speaker to produce sound constitutes labor because it creates a sound that did not exist before from electricity. Fluidics is able to get around this prohibition and can amplify sound in the range of human speech.
As far as molecular nanotechnology goes, some of the first molecular computers we may see might resemble the BZ media mentioned in the article. Right now we can make a whole range of interesting molecular devices including logic gates and motors among other things, but it is difficult to put them together into larger devices. It's hard to hook up a molecular motor to a molecular wheel to a molecular suspension to make a molecular car[2], much less wire up a bunch of molecular logic gates in a defined pattern to make a molecular computer.
However, it is significantly easier to make periodic structures. Metal Organic Frameworks(MOFs) offer a way to organize molecular machines into periodic structures. They are pretty great for this because they self-assemble and have a bunch of open space for molecular machines to move around, but still close enough that they can interact with each other.
Some researchers have proposed that we could use MOFs with molecular machines in them to make cellular automata with mole quantities of cells.[3]
