I never liked having to install Flash plug-ins. And I hated all the gunk that was created with Flash. So I quarantined a single older notebook to run the few Flash dependent apps that I needed to use from time to time. Ok, so much for my bias.
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.
