Math is not idle talk. You are idle talk. Math is math. If you want to prove your point, take a projection and mathematically show why it is not accurate. Since you cannot do this, your further assertions that projections are idle talk is actually the only idle talk happening here.
Triple lol. Could you please be so kind as to first show how are you going to describe real world events with math? A theory of chances? Okay, but what will a possibility of a given long-term projection outcome (100 years, as you said) be if you take into account the possibilities of
changes in the factors that may and will actually happen during that time span? Infinitesimal or just laughable? Let's get real, after all. And how on earth are you going to factor in the events which you can't even imagine (to happen), i.e. can't account for altogether, but which, nevertheless, do happen occasionally, and more often than not with devastating consequences, wtf?
Math is math, and it points a finger at you
Here's an overly simplistic example:
Known oil reserves: 6 trillion barrels.
Global oil consumption rate: 100 million barrels/day
Oil supply: 60,000 days, or 164 years.
Then apparently you say: that's dumb. But you provide no mathematical basis to contest it, yet you just keep saying the math is wrong because.
If you don't understand what a projection is or how to do math, then commenting on how useless projections are makes you look foolish. Now as I said, and you keep ignoring, a projection takes into account everything we know right now and includes likely material changes that could impact the estimate. It could change in either direction, or not at all. That's completely irrelevant. What matters is how long we project the oil supply to last, because that determines economic priorities in an oil-based global economy. How that number changes over time as we get new information is as important as the number itself because it indicates whether and how quickly things are deteriorating.
Go read a projection ffs. They give a baseline and then a range based on likely changes, in both directions, so that they're giving an overall range that's statistically viable. What's clear is you're completely unfamiliar with economic modeling, but you naively continue to sit there and say "nope" and base your assessment on nothing but ignorance, coupled with a steadfast refusal to learn.
