Hello,
Such a calculation is misleading.
I explain, in the real world all chemical reactions occurs at same time.
But in computer calculation , it's a simulation with our scientific comprehension of the phenomenom.
There is another problem what is exactly the purpose of this calculation simulate all chemical reaction or only a part ?
If you simulate all reaction .. we should use chemical quantum theory.
If you think that for hydrogen computation there are only one electron that interract with atomic nucleus ... for carbon you have 6 electrons who interact with nucleus .. but also with other electrons ...
so, if quantum calculation is easy for hydrogen
1 orbital 1s1 ...
with
carbon
1s2 2s2 2p2
electrons on orbital 1s interact with electron on 2s and 2p
2s interact with 1s and 2p
2p interact with 1s and 2s

If you think that we cannot compute exactly with math more than 3 electrons
but the real world made it ...
and this is only one atom ... a little protein in living cell has 100 or 200 atoms ...
The problem is not the "complexity" that we think to see here but what we want to simulate and the tools we use ...
At the other hand ... we could simulate these reaction in a real living cell when we
modify one thing at time ...
The reaction will be immediate but the time to analyze resulting data could take time ...
with computation ... calculation take time and analyze resulting data could be fast
To see a tree is immediate , study a tree take time , even without calculation or theorical work ( see botanist work :) )
or comparing real world of airplane and FlightSimulator :)
To conclude, it is an interresting work , but it could be misleading to compare real world
to simulation and conclude that complexity is a problem for evolutionist ...
It's not the same world, nor the same reality, nor finality ...
Best Regard
