Hah. To be honest, 2023 is going to be insane. I'm sure hundreds, if not thousands, of companies are going to emerge which greatly improve the software development process.
I think the software development process is fine, it's all the organizational cruft that slows it down. Your company is a good example of it--you probably didn't use Second to make Second, and being a solo dev had to have been a huge benefit to your velocity.
The things that hurt software development are people/process related, and can't be fixed by software, IMO.
Funny enough, I did use second to build the authentication flows. But I've diverged a bit because I haven't had a chance to fully build out the other modules that Second will need.
I'm planning on rebuilding Second with Second as soon as I have all of the appropriate modules in place!
