Had my first triathlon for years today, a local Olympic Distance event. Standard service was in play though as I was 55/109 overall but 19th on the bike split 
really hope one day to get a TT/Tri bike as that might help eeek out a bit more time.
So great to be back in a proper event/race again!
A jealous fellow triathlete here…it’s still a couple of months until een can race again
Great result and have fun picking a tt bike.
Just need to keep feeding the piggy bank
Fantastic job! I’m another fellow jealous triathlete. I can’t wait to get back out there in 2022. Sounds like SUF really helped you do the job on your bike split! 
Well done!
Unless you have a bundle of money or you think that you’re really going to do a lot of triathlons and TT events, I can’t say I’d recommend the purchase of a TT bike.
I’ve never felt the need for such an investment and I don’t believe the performance benefit would take me to the “next level” compared to other improvements, e.g. running.
You could argue the same about most things we buy for cycling though I certainly won’t go out of my way to get one, but if at some point I can afford one I’ll give it a go. I quite like the idea of doing some local TTs as well.
I found purchased improvements from oval rings, wheel and tyre changes, bike fit, etc.
Of course you are right that you can spend money everywhere 
I just couldn’t justify the one-time cost for such a bike when just enjoying my outdoor riding (cruising, enjoying the weather, etc.) was worth more than a TT bike which seemed quite restricted in its use.
Nice to have N+1 dreams, though
As a tt bike owner I’m biased of course 
I use my tt bike quite a lot, fulltime trainer bike in winter and TT’s and tri’s (when we can start again) it’s definitely fun to ride around on.
One thing that helped my performance a lot is the way I could change my body position and reduce drag. I did a bike fit for that. You could try to get the same position on your road bike but for me that ment new stem/seatpost and would change the road bike a lot. I cannot comment on being faster as I started training more after the purchase of the bike.
So while I would agree that you don’t need a tt bike, you really have to have one
