When I was a kid, nearly everything had a clear and simple way to turn it off. Switches flipped down to cut the power, and knobs clicked off when turned all the way to the left. You always knew if your TV was on, even if the screen was still dark, because the tubes were warming up. Radios were the same way. Before transistors came along, they ran on vacuum tubes that needed a moment to heat up before any sound came through. And you didn鈥檛 have to worry about it accidentally being too loud or soft. A simple knob controlled the volume.
Even telephones had unambiguous signals. When the handset was resting on the cradle, the line was closed. The phone wasn鈥檛 in use, and no one could possibly hear what you were saying. And if someone called, you definitely heard it ring. You didn鈥檛 have to worry about accidentally placing it in 鈥淒o Not Disturb鈥 mode. Not only that, you always knew where the phone was 鈥 it was attached to a cord.
Lights, vacuum cleaners and everything else that plugged into the wall had a physical switch.
Ambiguous switches
Fast forward to 2025. The same buttons that turn on my PC, phone, and TV also turn them off 鈥 but rather than having an on and off position, they鈥檙e just push buttons, and you can鈥檛 tell if they鈥檙e on or off by looking at them. Not only that, sometimes you aren鈥檛 even sure if you鈥檙e turning something on when pressing the button. When my Google phone goes dead and I plug it back in, I have to keep pressing the power button and wait for the battery to get a little bit of a charge before it turns on. Life would be easier if I could just flip a switch to the on position and wait for it to power up, just like I waited for my childhood TVs and radios to warm up.
And even though it鈥檚 unlikely to cause immediate damage, you鈥檙e still advised to properly 鈥渟hut down鈥 a PC or Mac before turning it off. That allows the system to close programs correctly, save its state, and avoid potential data corruption.
Many stovetops and other appliances now have touch-sensitive controls rather than physical knobs. I鈥檝e sometimes found myself struggling just to turn my induction stove on or off. There鈥檚 no satisfying click, no clear position 鈥 just a flat panel that may or may not respond.
Once devices like phones and tablets are up and running, you have to control them with your fingers. Good luck if you鈥檙e wearing gloves, but even barehanded, there have been times when my phone simply doesn鈥檛 respond. There鈥檚 no button to press, no alternative input, just a screen that decides whether it wants to acknowledge you. To turn off an iPhone, you have to press two buttons simultaneously and then slide your finger across the screen. I鈥檓 very tech savvy, but I had to Google how to turn it off and sometimes forget.
And 鈥渢urning off鈥 a device doesn鈥檛 always mean what it used to. Pressing the power button on my smart TV remote doesn鈥檛 shut it down 鈥 it just puts it to sleep. It鈥檚 still quietly drawing power in the background. That so-called 鈥減hantom load鈥 might seem small, but over time it adds up. When I remember, I try to unplug things before going on a long trip, not just to save a little electricity, but also to guard against power surges. Unlikely as they may be, a surge can still fry electronics that are plugged in, even if they appear to be off.
Even dimmer switches can be confusing. One of my rooms has a push-button on/off switch paired with a separate slider to control brightness. I thought I might need cataract surgery because the room seemed so dark, until I finally figured out how to adjust the dimmer. And just to make things more confusing, the light gradually fades out when you turn it off, so it takes a few seconds before you know it鈥檚 really off.
Are they listening?
Some devices that appear to be off are not only on, but they鈥檙e also listening to what鈥檚 being said in the room. Smart speakers like Amazon Echo, Google Nest, and Apple HomePod may not have an on/off switch. Unless you disable the microphone, they鈥檙e always listening for their 鈥渨ake word.鈥 Sometimes, they even respond when you don鈥檛 say it. But it鈥檚 not just speakers. There are smart displays, smart TVs with voice control, and of course, phones and tablets always listening for 鈥淗ey Siri鈥 or 鈥淗ey Google.鈥 I have so many of these devices that they sometimes answer at the same time if I say the wake word loud enough for other devices on the same platform to hear.
And don鈥檛 get me started on my smart car, which not only listens and talks to me, but also changes lanes on its own. I could turn that feature off, but I haven鈥檛.
Even my lightbulbs are 鈥渟mart,鈥 connected to Wi-Fi and always in standby mode in case I say something like 鈥淎lexa, turn on the lamp.鈥
Although I鈥檒l admit I鈥檓 being a bit curmudgeonly, I鈥檓 not really complaining. Modern technology is remarkable, and there are good reasons behind many, although not all, of these design choices.
Still, there was something comforting about the old days, when on meant on, off meant off, and our appliances and cars couldn鈥檛 eavesdrop or talk back.
