Well the other issue though is that people looking for predictions want conservative predictions because they're investing. Over-estimate and you lose money, under-estimate and you leave money on the table but don't trade away future possible gains.
Hum... People investing in renewables and batteries do not use predictions. Those have at most some 3 years of building time, usually a few months.
People investing in fossil fuel plants need predictions, and despite they wanting to see conservative numbers, that bias means complete doom for them. They need the opposite bias if they want to survive.
Things get a lot more complex once you start to look at components industries. But then, it's not clear they use predictions for anything.
