Passive cooling is generally better for reliability if you can make it work, since all active airflow systems will degrade as dust and hair works into the airflow paths.
Plus, the two can be used in combination. Improved passive cooling systems will make active cooling better by reducing the need to run the active system all the time, or at least run it at reduced rates, which will make the whole system last longer and reduce maintenance.
Counterpoint: stop trying to make laptops thinner and implement realistic and functional air cooling

But this system still makes airflow right? Just without moving parts.

Make the chassis out of aluminium so the whole bastard is a heatsink.
Apple has been doing that for years
Slaps roof of laptop This bastard can cook so many egg omelettes
Two eggs and one sausage
My laptop and older phone has this and it really does help with the added surface area.
The only issue is if you go full throttle, the section right above the CPU can fry your hand lol.
Although I only ever reached that temp doing stupid crap like hashing.
Or we innovate 🤷
It isn’t a given that every device needs a fan anymore. For example non intel MacBook air.
