Good article in general, but I would have put more emphasis on EROEI.
If you take into account the 3% to 3.5% rate of deterioration in EROEI since the hay days of the 1930's, you see it halving every 20 to 25 years. If we are now at 8 to 1 worldwide, meaning we lose 12 1/2% of each barrel as cost, then by around 2035 we will be at 4 to 1 worldwide, meaning we lose 25% of each barrel as cost. Just after mid century we come close to losing 50% of each barrel as cost. This is a devastating progression of increasing costs. Who cares what production will be; it is the relentless doubling of cost (halving of EROEI) that will destroy economic output and the lives of those hopelessly dependent upon it.
In the early days of oil production who even noticed the effect of doubling cost. When cost is 1% and doubles to 2% that is a miniscule change. But as we move along the progression, each doubling of cost becomes more significant (1%, 2%, 4%, 8%, 16%, 32%, 64%) so that in the late stages we seem to fall off a cliff.
I suppose the same principle is working when a human enters the latter stages of his life span and seemingly deteriorates quite rapidly. Oh, the wonders of the laws of nature.
