I’ve been iPad Pro only for the last 12 months or so, can countnon one hand the amount of times I wish I had a computer to use - in fact only times that come to mind is when I’ve found an Oldbury iPhone that needs connecting to iTunes to reset it correctly, other than that iPad only works perfectly for my needs
 
Honestly, no.

At least not without access to some kind of backup computer. There will most likely be cases where you need an actual computer.

I tried to replace my old MacBook Pro with an iPad. I had to fall back on my iMac several times.
