It's a bit easy to imagine once something's already survived it. A device with a hundred sensors probably survived hundreds or thousands of failed released or unreleased iterations. Every other mature field has probably gone through this same sentiment (and maybe still going through it, and perhaps will always go through it). If only astronomers today could imagine what new, novel techniques are just lying right in front of them with all of this computing power and automated manufacturing ability. Imagine how much further ahead astronomers would be in 2044 if they had discovered thingamajig back in 2014 instead of 2040! I think the greybeards of 2044 would be a bit biased.
But this feels like we'd be backpedaling on choosing the right tool for the right job. Slapping AI onto something and watching it fail is great for our knowledge, but not our wallets. This is when business leaders create friction with development. This is where you get "Just make it work" commands which gets the snowball of technical debt rolling. The value gained is "This solution sucked in reality! Or maybe we just sucked delivering it! Don't do what we did unless you have a good reason!", but that's not what we're really after, is it? We could sit around and brute force a bunch of combinations of ideas and markets, I guess.
And finally, if it was true back in 1985 with domain names, and it's true today with AI and the cloud, why wouldn't it be true for 2044 with VR contact lenses and holodecks? It seems like the future will be like then and now in this regard. So.. there will always be a wide open frontier somewhere? Do we really say anything substantial by saying "Today's an open frontier for internet ideas!"
I think there's a lot less low-hanging fruit than this article might have us believe.
