I bet the majority of people here put more than 3800 mile on in a year.
My son has a 2008 Cervelo TT bike and I would guess he has well over 50,000 miles on it. He's swapped groupsets a few times but its the same frame.
I have 26,000 miles on my 2015 and while i've replaced the bottom bracket, chain, tires and brake pads, i see no need to replace it. I upgraded from Sram Red 22 mechanical to eTap electronic and glad I did. You want Di2... go for it.
