I think that you overestimate machines
There is a chance to draw or to win them because of erong opening line.

I know also that they do not see everything even about tactics and there are
tactical lines that even 200M nodes per second are not going to help to find if
there are not software improvement(see the draw that deeper blue did not see in
the second game against kasparov).

I believe that 100knode per second is enough to see everything that humans can
see if you search the right lines but programs do not know to search the right
lines.
