Not much as much as you think, apart from the routers, computers and phone, the only other thing I can think of is the dishwasher because it's half-recent. And I suspect the new ones just include a cheap Android board. I suspect you’re thinking at the wrong level. Your washing machine definitely does have software even if it’s not “recent”. When you press the buttons or turn the dials and it does stuff, even if it doesn’t have pretty graphics on the display, that’s software. If you have a microwave, that has software, if you have a car that has a ton of software. Your car keys and your credit cards probably have software.
