I once saw a YouTube video of someone building a Starcraft-like game in under an hour using AI. When things like that become normal, I can totally see "why pay for it when I can just build it myself?" becoming the default mindset.

But I think this will naturally correct itself once companies start tracking AI costs seriously. If AI tools become standard in the workplace, the new performance metric could become something like "how few tokens did you consume to get this done?"

Once people start thinking in terms of token cost, rebuilding existing products from scratch every time starts looking pretty wasteful. At some point the token bill for repeatedly reinventing the wheel just exceeds the price of buying the proven product.
