computer program?.....or real cards?

I am sure everyone notices the difference between playing hands in a real life tourney at the local casino and internet poker hands.....internet play follows the program....you may get a run of winning hands then you may have the best of cardsin your hand with matching flop cards but you lose to stupid opponents hands on the river.
It is difficult to explain...but you must have noticed this....
Sureley programmers can write programs to give us.."real play"?
What do you all think?.....or is it a necessary part of poker site control and profitability?...I play both often and can see a marked difference in gameplay....do you??

The problem is.. the computer is more random than real cards. Due to this we see outcomes that seem absurd, but simply because its more random than normal dealing in which we don't see certain hands...

odds and statistics will work out that we see a lot mroe massive hands online beacuse its more random which in fact makes it less random if that makes sense.
