Technology is always being changed and improved, to the point where it can be difficult to keep up. Computer technology in particular is rendered obsolete so frequently that the computer you buy today will be inferior almost as soon as you take it home. The computer progression model isn’t true for every kind of technology though. There are some inventions that are heavily used every day that look a lot like what was being used decades, even centuries, ago. Technology will always be progressing, but these 7 technologies never really had to.
We sit on these thrones everyday and they’re an essential component of our daily lives. Besides their practical purpose, there’s a very good reason that the toilet you use today looks a lot like the ones you’ve always used. Other than the introduction of flushable valves and water tanks that made the modern toilet a reality in the 20th century, there hasn’t really been any need to push toilet technology any further. Sure, they have become much more efficient in terms of water use — and some even have fancy levers and designs — but today’s toilets are for the most part identical to what they were 100 years ago.
