With Chrome dropping support for Flash in January, and there being no universal support for any other standard yet, I was curious to see if anyone had any guesses as to what the next might be.
Technology has moved on a great deal since Flash was first released to address the shortcomings of the HTML standards of the day. We now have WASM, HTML5 and ES6. For games there are both 2D, 3D canvas operations and SVG. From an infrastructure point of view, support is far better than Flash is able to offer in 2020. I expect that authoring tools will catch-up and surpass what was possible with Flash tooling.
