>The web is unable to deliver an experience like Flash could
I think the browser has been on par with Flash Player for a while, but Flash-the-authoring-tool (to my knowledge) does not yet have an equal. (I'm told Adobe Animate, the rebranded Flash authoring tool, is somehow unsuitable for creating games, despite HTML5 export features.)
To put it another way, I think we've more or less replaced the Flash Player, but we haven't replaced Flash Professional. (As others have mentioned, Unity kind of covers the same ground, but not really.)
