I don't buy into the upgradeitis that so many have with their phones. I have an iPhone 7 with no intention of replacing it unless it stops working for me. Same goes for my bikes. I have two. One road, one mountain. The road I bought around 2000 or 2001. The mountain I bought in the mid 1990's and upgraded it over the course of about 5 years, and more than doubled how much money I had into the bike during that time. Both bikes put a smile on my face when I ride them. So, I see no reason to go out and buy new ones. Of course, my feelings may change tomorrow as I look at all the bike porn on this site.
