    Self driving cars. Ten years ago I said, “we’ll have this worked out in 10 years”. What a fool I was.

      Elmo has claimed to have it for over 10 years now

      You weren’t a fool, you simply were lied to

      Elmo always lies, every second word put of his mouth is a lie. Every project he boasts about has been a lie.

    Brit on a train; A phone network that would offer a reasonable level of connectivity no matter where you are in the country.

    Ours definitely took a few steps back early 2023.

    I thought that by now we would’ve commercialized at scale alternative battery technologies. We’re still using lithium ion even for grid storage and EV’s.

    Also, I expected we would have put a man on the moon by now.

      We wouldn’t need such a battery development if we had simply invested in a standardised electrified wiring network for the motor roads. we would have lighter cars that charge their ~100 km battery while driving on the motor road so they can easily reach their destination

        Maybe give cars a second pair of axles, to keep them aligned with the overhead power on the highway and to reduce the tire wear. Maybe join them together too so each individual car doesn’t have to worry about braking and the driver can basically just sleep.

        This isn’t me sarcastically reinventing trains. I see why people would rather spend their commute in a private car than in a public train carriage. These features just seem genuinely useful.

        What I have sarcastically reinvented is basically just self-driving cars.

    I was hoping that by now technology and education would have helped all the humans to realize how to take care of each other and work together for a better tomorrow.

    Instead we got this fucking mess that’s going on right now all around the world.

      It’s really that. All that technology and we still didn’t solve the most primitive and basic problems in this world’s community.

    More of a pet peeve, but I thought IT would be way more stable by now. Everything has so many bugs and it’s just accepted. I’ve grown pessimistic about new tech and I would prefer to wait a couple years before getting it. It’s not novel if it’s broken.

    Side thought, I thought we would have hologram phone calls by now.

    Computer phones. As in I just connect to screen and keyboard, and phone is my main desktop.

    Cheaper EVs.

    LED light bulbs were supposed to last a bajillion hours. When they came out around 2010-ish they were still expensive and I spent many hundreds of dollars replacing every single light bulb in my house, thinking I would basically never have to replace a light bulb again.

    It’s 2026 and I now replace the LED bulbs in my house almost as often as I replaced incandescent bulbs. Seriously? LEDs are solid-state technology. There are no moving parts, no gases, no hot filaments…

    I understand that it’s probably on purpose; if everyone replaced all the light bulbs in their house with LED bulbs that lasted basically forever then who would buy more light bulbs from light bulb manufacturers.

    But it’s still just dumb. Either LED technology is flawed, or our economic system that incentivizes a constant cycle of replacing bulbs is flawed. This should should not exist in 2026.

      Oh that’s a fun one. Original incandescents lasted a very long time. Too long (over 10,000 hrs, and there are many examples of ones that have been lit for decades!). The various manufacturers actually conspired(spent a lot of money on research and development) to a 1,000 hr operational benchmark. Profits exploded.

      This is common (engineered predictable fault.)

      no hot filaments…

      There may not be filaments, but heat is still an issue for LEDs.

      Some bulb manufacturers basically overdrive cheaper diodes to get extra brightness at the cost of generating extra heat. Some of those manufacturers compensate for the heat in some way, others don’t even bother and produce bulbs with a service life of months instead of decades. Some of these are fly-by-night online sellers that won’t exist anymore by the time their products start to fail. Others are established brands that people will blindly purchase based on a reputation that no longer matches reality. There are some reliable brands out there if you read up on it, but why the fuck should we have to research every little inane item in our life?

      Aside from corporate greed, though, there are other reasons heat causes early LED bulb failure. Two common ones are incompatible devices on the same circuit (like light dimmers), and installing the bulb in an enclosure without adequate heat dissipation (like a ceiling ‘boob’ light).

      I’ve been all LED for well over a decade, and have had a good experience so far. I personally tend to buy smart bulbs that can put out way more light than I need, and run them at 20-50% brightness most of the time. Feit Electric and Govee’s basic smart bulbs have been pretty reliable for me, but I admit I’m a pretty small sample size. I know I’m paying a premium for that approach, but it’s not unreasonable and I do prefer not having to worry about it.

      Something is wrong with the ones you’re buying, then.

      Studies show that they do, on average, last dozens of times longer. Personally I replace them way less often than incandescent.

      I suppose the earliest ones were worse and there are definitely garbage ones out there. And even good brands have a did here and there. And if you have poor/inconsistent power, or placing them in hot, enclosed fixtures, they don’t perform as well as they could.

      From my experience, what tends to get messed up is the internal wiring. The actual leds will continue working fine, but cheap/shitty wiring will make the lamp stop working

      Buy dimmer, filament style LEDs. They don’t burn themselves out hy heat at least.

      Otherwise you’re facing planned obsolescence.

    I thought we would be able to redo our dna in adults using viruses or other vectors completely. Where we are now I thought we would be in like 2010. So we are making progress but I thought we would be farther along and genetic disease would be a thinf of the past.
