Most other people lack the prerequisite skills even with Claude at their disposal. And it was always the case that other people could copy your things, it's just the effort was much higher, now it's more accessible.
Regardless, I would suggest you don't let this deter you from bringing something new into this world. It might have enough value to make it all worth it. Or not, but not releasing it you won't find out for sure.
But on the other hand... The things we really believe in we'd still cheer if someone else executed the idea better than us. Sure, we might make less money, but the idea gets to live.
And the odds of someone executing better didn't really go up, ai is just average across the board. So at worst, the odds of someone executing our ideas as well as us went up. Could be worse.
For me, I moved some money out of the stock market. The PE ratios are just too high to make sense. (I mean, I think that the competition is bonds, and the interest rates on bonds being lower means that stocks can support a higher PE. Still, I think the current level is probably insane. I especially suspect that AI stocks are going to get hammered, so I reduced my exposure there.) But I didn't get completely out; for medium- to long-term money, I still want to be there.
Could I miss some gains? Absolutely. But I also could dodge some losses.
