This is true if you make naive assumptions like making circuit boards are a clean technology with no CO2 emissions or other harmful side effects. That of course is entirely incorrect. Printing circuit boards are very energy intensive along with a lot of other impacts like toxic waste and heavy water use. > In the US, a single fab, Intel’s 700-acre campus in Ocotillo, Arizona, produced nearly 15,000 tons of waste in the first three months of this year, about 60% of it hazardous. It also consumed 927m gallons of fresh water, enough to fill about 1,400 Olympic swimming pools, and used 561m kilowatt-hours of energy.

Kombucha on the other hand, yes produces CO2 as a waste product, but it is very easy to see a kombucha SCOBY being carbon neutral. That is the source of it's sugars being carbon energy free, and the manufacturing process of SCOBY circuits as well. Then it's carbon neutral
