Both of your examples, more users and better titles, can absolutely be technical improvements. Both of them could be, for example, improved by using machine learning to attract more users by appealing on an individual level and doing things like optimizing titles for the individual and pushing those individualized results out.

I'm sure there are even more technological advancements that can be made - and I suspect there always will be.

I'm not saying that it is currently ineffective, just that it isn't solved - meaning that there are still solutions to improve efficiency and efficacy. I actually see 'solved problem' as a kind of defeatism.

I think using AI to make clickbaity titles is still sigh-worthy.

In theory, it doesn't have to be evil. In theory, it could be good to attract users to information that benefits them and increases discoverability for that purpose. In theory...

The same thing can be said about spam. It could be good to be able to send useful information to users right to their inbox while avoiding being detected as "spam".

In reality it's mostly just dark pattern marketing.

Well, maybe we could use the news to make more people aware of it and help mitigate human behavior? ;-)

But, yeah, it can be used for nefarious purposes. In fact, it probably will be. Hidden under that will be good uses.

I suspect there's going to be constant innovation. There are people who thought that personal transportation was a solved problem back when we rode animals. These days, we are looking at an EV revolution and SDV somewhere in the not-too-distant future. Along the way, it hasn't been a solved problem, even though it looked like it was.

I guess that's what I've been clumsily trying to say.
