What if we rely on AI for the one thing it’s definitely not good at?

Don't even know if I should build some LLM-powered tools to fight back magic with magic, or if I should just quit altogether.
Agents create the illusion that you can accomplish complicated work with simple prompts, and people become less appreciative of the hard work behind the scenes.

When running my own startup, we used to have a saying: A deal is only a deal when the money is in the bank. Handshake, contract or commitment mean nothing.
OpenAI’s spend commitments have crossed a $1T with no sign of stopping. It’s committed to spending up to &25B on a data center in Argentina.
Their revenue growth is either going to be spectacular or there’s going to be a spectacular amount of bounced checks. Either way, it’s going to be impressive.

This could have been Australia, but thanks to John Howard, Tony Abbott, Scott Morrison, the Minerals Council and the BCA, we wasted nearly 20 years subsidising gas and coal instead. What a waste.
China ≠ just coal plants and solar exports. The deeper shift: electrifying everything it can. Strategic, because China relies on imported fossil fuels. Coal is still king in the power mix—for now. But the balance is changing year by year.
