Very true, I underestimated the time required to even build a small library, let alone the full stack signing app I've been building. I have way more time than most devs too (less experience). It's come so far in a short time, but as usual when you look under the hood you can see how glued most applications are.
To think most apps were built in spare time, without funding, nostr is one of the most exciting and impressive environments I've been around.
