I was thinking about this... I've built our family's financial system (it started as a simple budgeting tool, but now it tracks everything), a Mac app to create and edit videos, quite a few developer tools for personal use, a bunch of apps for my kids, some games, and so forth.
All of these already have plenty of commercial offerings in the market, and some have open-source alternatives, but the level of personalization I get by building them myself beats any argument (IMHO)!
Interested to see what others are doing. :)
PS: I've been writing software for 8 years (5 of them professionally).
It is really possible to build software by one person. I have built 2 software recently. One is debate platform for high schooler. One is essay inspiration web app. Both for my son.
It was impossible to built with IDE manually in such short time.

It's never been easier to get nerdsniped into silly work.
Doesn’t mean I don’t use existing code. In fact, LLMs tend to be great at finding existing libraries and reviewing potential sources should always be part of your prompt. Writing code from scratch is good for prototyping, but existing libraries tend to be much more robust and battle tested
