This might be a little exaggerated, but I definitely have felt the same way at times:
Maybe its just me, but the only time I want to talk to a device is when I’m in the car driving and can’t look at the screen.

Since Siri came out, there has been a weird tension surrounding when I’m comfortable having a conversation with my phone. There have been many times where I wished I could just type out my request.
Spotlight exists for typing in search requests, but it’s far more limited that what Siri can accomplish. These two systems seem to have some level of overlap, and some minor tweaks to Siri could obviate the need for Spotlight as a separate feature. Siri could also benefit from a lower impact gesture while using your phone, such as Spotlight’s swipe down on the homescreen, as opposed to a long press on a physical button.
The requirement for spoken requests could be holding back Siri, and I’d personally love to see it become more accessible.
