I think you are making a good point, but there are definitely some important reasons to consider as to "why" Siri is lagging behind. Privacy might be the thing holding Siri back.
Google Assistant has taken a different approach that I think might be giving better performance than Siri. Google will likely keep on making their Google Assistant better and better, and try to play down the "privacy" issue. I think most people care so little about privacy in reality, that this strategy could continue to work for Google. Nobody seems to care about privacy and Google knows it - they may have the winning formula.
Siri is crippled by taking this high road of protecting end user privacy. I wonder how Apple will do better while still protecting privacy.
I certainly hope Apple Siri developers do not have their head up their "you know whats" and can get Siri to do some pretty basic stuff a lot better. For instance, why is it so hard for Siri to pop up a tap-able phone number when responding to my query for a retail establishment? I end up telling Siri ( on the second try ), to "search Google for ______" and Google shows me what I wanted AND puts a clickable phone number..... Was that such a hard thing to do that Siri and Apple cannot do it? Why am I forced to have to do the Google search to get such a thing happening? Siri Developers better get some feedback from real people living in smaller cities etc...... I just have a feeling that lately the developers are all satisfied with their work, because maybe all they seem to search for is "Starbucks" or something and are missing the fact that if you search for something that is not a big box store or big restaurant chain, you get bad results from your Siri search whereas a Google search gets you what you really wanted....

I also love using Siri for dictation. I almost NEVER type a text message, it's so much faster to dictate with Siri. That's one thing that Siri is really excellent at, I agree.
