What kind of Muggle technology would the wizarding world use in 2022?
The following Muggle technologies are the most advanced technologies mentioned in canon:
cars (although adapted with magic)
radios
escalators and elevators
indoor plumbing
radio (but not telephones!)
cameras
I've heard people mention zippers, but I can't remember where in the text a wizarding-made garment is mentioned that explicitly features a zipper.
The latest of the inventions, excluding the zipper, are the escalator and radio, circa 1890s. The basic concept of the zipper was first created in the 1850s, but zippers were not fully developed or commercially available until roughly the 1910s. In the absence of canon evidence for wizarding zippers, I'm going to exclude zippers from the conversation and suppose that the latest Muggle technologies to be integrated into the wizarding world originate around 100 years prior to canon, in the 1890s.
Following this logic, wizards living in 2022 would, by now, have also integrated Muggle technologies from the 1900s to the 1920s, which might include:
frozen foods
vacuum cleaners (though probably unnecessary in a magical context)
the assembly line or industrial production of goods (also likely unnecessary)
washing machines
film
dishwashers
refrigerators
toaster
electric irons
I believe this would make Arthur Weasley very pleased. However, we are unlikely to see the wizarding cellphone or wizarding Google until the 2090s.
