Inspired by @gwern's list of everyday life improvements (gwern.net/Improvements), here's a thread documenting changes that I've noticed in my lifetime.

Start with cars: key fobs! When's the last time you locked your keys in your car? I used to do it at least once a year, but since getting a car with a key fob it's never happened. Plus the new "proximity unlock" feature is incredible when your hands are full.

Also: heated seats! Sitting in a cold seat while waiting for the car to heat up is miserable, and heated seats are a real gamechanger for cold climates.

Headlights that turn off/on automatically. I used to need to jump my car 2-3 times a year, as I would forget to turn off the lights when I got to work. Hasn't happened once since we got a car that automatically manages the headlights for you.

Motorized doors! When I was younger I scoffed at these, for reasons I can't entirely recall, but now that I have a minivan with automatic doors/rear hatch, I wouldn't go back. They're easier to operate while holding something and allow children to open/close doors on their own.

Backup cameras are another innovation that I dismissed until I had one. In particular, they make backing up to hitch a trailer at least 10x easier.

Proximity alarms: I can back into tight spaces much more confidently knowing that the car will let me know how much space I have between me and whatever is behind my vehicle.

Alarm clocks: Remember that you had to buy a separate device just for waking up? I got one of these before I went to college and remember thinking that being able to set a different alarm for each day was a HUGE gamechanger. amazon.com/Patch-Products-LLโ€ฆ

Smartphone cameras: Having an amazing camera always on your person with effectively unlimited storage completely changes the way my life is documented. I think my parents have 20 pictures of the first year of my life. I took over 50 in the first 6 hours of my kid's existence.

My children are going to have almost every day of their lives documented with photos, which I am very jealous of. I wish I could look back at a complete timeline of my life like that, there's so much that I've forgotten about.
