I'm looking at prices on the French Apple website and it says
7 cores GPU / 16GB RAM / 256GB SSD 1.359 euros

I'm not saying it isn't the price people will pay, I'm only saying it's a price point that will convince people to upgrade, but won't allow Apple market to expand in a meaningful way.
Apple had already a boom years ago, I still remember Peter Jackson editing LOTR on set with his MacBook Pro + Final cut.
Then Apple stagnated and studios replaced their Macs with PCs.
Now maybe they will buy Macs again, it's a cycle, it's the same market shrinking a little and expanding a little over time.
Pro Macs are not iPhones, there are countless alternatives.
