Vibe coding UI elements one-by-one is too slow of a process. Currently playing with Stitch to mock up a full design first, and then have GPT produce code from the image.

Pretty crazy how the world just keeps moving the same way while we have so much technology ready to do things differently. Inertia is the biggest anchor holding us.

AI is leverage for small tasks, not a replacement for you.

COVID19 isn't the flu. But for under-45, COVID hospitalizes 1% & kills .014%. All ages, flu hospitalizes 1.5% & kills 0.13%. Restricting COVID to under-45s results in 6x flu hospitalizations & 1x flu deaths, & gets us to herd immunity. Shelter the old, but release the young!

There is a faster way to reach the Windows Task Manager than hitting Ctrl + Alt + Del and click. Ctrl + Shift + Esc #windows #shortcuts #lifehacks
