A question I always ask is why we can't control our phones via desktop computers yet. It's 2024; this should be possible and mainstream without half-baked solutions like Airdroid or unacceptable workarounds like rooting your iPhone.
I sit in front of a full-size keyboard and mouse literally all day, yet when I need to do something on my phone I'm forced to physically pick it up and use its horrible tiny little keyboard to achieve something I could achieve in 10% of the time on a PC.
