Yes, using tooling is literally what differentiates humans from the apes. Claude and the like are just the next evolution of tooling. BrewUI looks fine to me and I certainly prefer it (as it's native) over all the "hand-crafted" node/electron dumpster fires. If you want to continue to rub sticks together to make fire, nobody is stopping you (except perhaps the market).
No, you have a primitive understanding of evolution. Apes literally use tools. And if you want to play with AI fire in the "crucial entry point to potential malware to my system", nobody is stopping you either (even if you trust your own ringing security endorsement of "looks fine to me"), but that would still not address the core point of this discussion
