This point on security is great point that I have not fully appreciated until now. I have been telling people that my own ability to use claude code has been a game changer for what sort of tools I will or will not pay for or use. This includes random self host services.

For personal use, those making their own software will still be a minority for a while, but at my job we are seeing potential to save $1M-$10M a year by rolling a custom tool vs paying for a commercial one. The saving here come from the tool doing a better job, not the license we pay.
