28 years working on Bean 2 Cup and traditional machines myself.
I like technology, modern ideas keep the coffee world fresh.
However, most of the systems you quote were designed to help get a better coffee from B2C (fully automated) machines because most of the early ones were truly awful.
If some systems have jumped the gap to traditional why not? "traditional machines are a lie" wtf is all that about? We're talking about a machine that makes coffee and like most machines they have improved over the years. Plenty of tech from traditional machines went the other way too? Do super autos lie about that?
B2C machines are still not up to the standards of a traditional machine with someone who KNOWS WHAT THEY ARE DOING stood in front of it -That my friends is the problem!
It turns out that a mechanism that replicates what a Barista can do with his arm is expensive, slow, needs regular maintenance and still isn't as reliable. As you say, they also need a lot of work to set up.
Add to the mix that the mechanism needs heating, a hot water supply from a boiler and a box to keep it all in and suddenly you have to add sensors, elements, cooling fans and a whole load of other stuff to try to get a decent coffee. The inside of a B2C machine isn't a great place to store coffee.
The problem, even with a well set up machine is that things change. Everything from the weather to the water has an effect - the biggest is the person stood in front of the machine. Unfortunately, B2C machines with their codes, keys and set-up training courses aren't too easy to alter when this occurs.
From time to time a supplier talks us into trying the latest B2C machine, hours of set up and experimenting ensue and eventually we think "wow, that's not bad". At that point, leave the machine for ten minutes then compare the next shot... Not been impressed yet. Don't even get me started on automated milk frothers, at best they are poor, at worst a health hazard!
Many coffee machine suppliers in the UK won't supply super autos for good reason. They are expensive, less reliable and less consistent at making great shots and therefore can get you a bad reputation. They just don't get used by anyone who understands and wants to produce truly excellent coffee. They simply aren't good enough...yet.
Even if they were on par with traditional machines would they be as popular? We all know coke tastes better from a cold glass bottle, tea tastes better from a bone china cup... Blindfolded we probably couldn't tell the difference but they are better!
