I don't mean the beginning of these tech decades ago. Currently these are outdated and beyond annoying and stuipd tech but billions use them. We can replace most but instead we choose the pain for no logical reason. What else to add to this list? SMSof them is so unsecure that causes real problem too. Millions ignore it instead.
For all its flaws, SMS is awfully hard to adequately replace because it's universal. Any alternative quickly gets you into a quagmire of having to install multiple apps (itself a security problem) and having to keep track of which app to use for which person.
What’s wrong with RSS? Half the people hooked on social media could replace their never ending feed of suggestions with a few RSS feeds that would let them stay up to date without spend hours scrolling through nonsense.
