Today in incredibly obvious things... Smartphones are an absolute graveyard of fads; remember the 3D screen phones, the phones with projectors, and so forth? They generally go nowhere. I suspect 'AI' on phones will be similar. Overwhelmingly, what people want out of phones is "like my current phone, but with better battery life and maybe a better camera." Previously 'faster' was also a concern, but modern phones are…
Even camera improvements are overblown. My usage and photo quality did not improve much since ~iPhone 6. Taking decent travel photos, selfies, etc - I was happy with the results 10 years ago. Technically, I understand the difference in the technology, I just don't know who needs that vs who gets excited about new features for a brief moment.
I would love to take a photo using my smartphone that doesn't look pixelated, blurry and or over-processed. Maybe asking too much considering smartphone sensors can't compete with DSLRs in some situations, but I'm always baffled with how dark and desaturated some of my photos turn out on my smartphone, as well.
