Food and Cooking

Cooking is an inherently manual task, and as such any meaningful improvements to cooking tools are enhancements to the manual capabilities of the tools. These are improvements to things like speed/precision/durability of mixing, heating, weighing, etc. Often times the most meaningful improvements are improvements in mechanisms in cooking machines or the materials they are made of, but there are definitely examples of electronics or software contributing in this way. Good examples would be fuzzy logic applied to electric kettles to make the act of heating to a specific temperature more precise by controlling the heating element so the water is brought to temperature without overshoot, or PID controllers in espresso machines controlling pumps to follow a specific pressure curve instead of requiring complex mechanical systems to accomplish the same thing. The problem with many of these internet-connected or heavily software-dependent appliances is that their added features do not improve the manual capabilities of the appliance in any way, sure the machine will tell you how much weight of flour you need for your cake, but your cake won't be better than one produced by a "dumb" machine because the scale isn't any more precise than any other scale that would be used for that purpose.

The other issue with these devices is a fallacy that's really common in kitchen equipment, which is the idea that more functions = better. Fundamentally, a device designed to do both task A and task B will be worse than an equivalently priced combination of one device for task A and one device for task B, because there is a cost associated with engineering the device to accomplish both tasks. This effect is especially noticable on all-in-one devices that mix, weigh, and heat because there's a lot more complexity, and thus a lot more cost spent on integrating the components together
