Mobile Devices → end of Flash, Silverlight, Moonlight, Java Applets, ActiveX

When it comes to browser plugin technologies like Flash, Silverlight, Moonlight or even old Java Applets, I claimed today in the early morn, that those tehcnologies began to die with the raise of mobile devices (most with a unix kernel) and mobile browsers. 

In fact it was the <object>...</object> tag in html, that whose full implementation of all technologies subsequently implied an excessively long and complicated process for mobile device and browser developers.

Died arround 2020 or earlier

There may exist some flash browser under android, 
but the came too late:

Html5 + Css with Javascript (TypeScript, Angular) remains

There isn't really an alternative for browser plugin languages we had.  Html5 + Css with Javascript and all derived JS Framrworks like Node.js, TypeScript, Angular cannot map all features of Flash or Java Applets.
