I don&#x27;t know what any of those things you named are. I ignore all that stuff. The only thing from the &#x27;90s that doesn&#x27;t work anymore is Flash, because I guess Apple blocked it during the mobile revolution and it killed its dominant position.<p>Otherwise, everything applicable from back then still is today. Any time anyone mentions PHP on forums like this, there&#x27;s always fashion-conscious people who jump in to attack it. But I&#x27;m still building brand new websites based on it, and people still express their gratitude, never once saying there&#x27;s any problem because the site uses PHP.<p>MySQL is still going strong, and there&#x27;s some alternatives that are compatible, like Percona and Maria.<p>JavaScript is the same. There&#x27;s all these frameworks like there are for PHP, but I ignore all that. I never understood why I&#x27;d be better off using someone else&#x27;s virtual language on top of a language. I just use bare JavaScript, and it works the same to me as it did back then. Still have to worry about differences between browsers, but instead of Netscape and IE, it&#x27;s stuff like Chrome, Firefox, and Edge. A framework can make that easier, but it can make others things more difficult, and it&#x27;s better to keep dependence on JS minimal anyways.<p>What I&#x27;m getting at is, I don&#x27;t know why you need to update anything. If you&#x27;re trying to get a specific job, then you need to use what they do. But for just building things in your free time that work on modern web browsers, you already know what you need to know. You could probably even run the same exact version of server and authoring tools you did before, and it should display fine in the latest web browsers.<p>It&#x27;s different if you want to build something like a mobile app, or Windows software, because those platforms changed significantly since the &#x27;90s. There&#x27;s languages now that didn&#x27;t exist then, and new tools you&#x27;ve never seen before.<p>But on the web, any text editor, HTML, and any language you want for the backend is fine. Just like I still write .sh scripts, and they get the job done.<p>It&#x27;s more important to spend that time on family, and your career. Since the stuff you already know still works, there&#x27;s not much need to use anything else. Unless you&#x27;re worried about what the kids think, and how they&#x27;ll judge you.
