How does this obviate the need for software? In order for what you asked to be possible, Word, Excel, PowerPoint, and Figma all still need to exist and you need licenses for them.
If you can figure out the next step and say "Claude, go find me buyers and sell shit for me without using any pre-existing software," have at it. It can't be social media, I guess, since social media is software and Claude is supposed to get rid of software.
At a certain point, why do we even need computers? Can't we just call Claude's hotline and ask "Claude, please find a way to dump $40 million in cash into my living room. Don't put it in my bank account because banks use software."
