Your nice little experiment only says one thing: the statistic meaning of "random" is 50%.
You had a problem with trends, I showed you that they spontaneously emerge even from complete randomness, I even showed you why the particular trend we were talking about
should go the way it went, and
that's what you take away from it? Something it didn't actually demonstrate, and was never meant to?
FWIW, the "statistic meaning of random" is
not 50%. "Random" simply means that the exact same starting conditions can lead to different outcomes. It's common for people to think that "random" means "everything is equally likely", but that's most definitely not true.
[Aside: a minor correction to the description of my experiment. There were only 999 generations in which complexity evolved, because I forgot to change some numbers in my code. Doesn't make much of a difference, but I don't like leaving errors in my posts

]
A nice exercise, nevertheless. I still want to go back the bacteria argument. If evolution is random, then bacteria should break through the unknown barrier and evolved into something which is not a bacterium. Why does this not happen in the past 4000 million years? Randomness can not explain it.
You are wrong on more than one point.
(1) I didn't say evolution was random. I said that even IF it were, trends would emerge.
(2) Randomness means precisely the opposite of what you say. If evolution is random, you can (a) never predict a trend with 100% certainty, though the larger your sample, the more certain the prediction; (b) even if the trend you predict goes according to expectations, you cannot predict which
specific lineages will create the trend. Just like if you flip 100 coins, you can be reasonably sure there will be about 50 heads and 50 tails among them, but you can't tell
which coins will land tails.
(3) Nothing ever evolves into something that is no longer "it", just like you can't just stop being a member of your family by changing your name.
That said, what would constitute "not a bacterium" in your eyes?
Nostoc or
Anabaena are multicellular organisms with at least 3 different cell types.
Oh, and bacteria contributed hugely to the origin of eukaryotes. Ever heard of
these guys? If the eukaryotic cell doesn't constitute "something else", I don't know what does.
