Not quite. We can breed any elements we want if you want
to devote enough energy to it. However, the rate of production
is *very* slow. You also have to sacrifice energy for current
thought to produce the elements for enhanced future thought.
I would not want to be the person responsible for the present-value
analysis of that equation!

Yes, as soon as you max out your solar system in terms of
energy/materials, your growth rate declines sharply.
Though it remains interesting in terms of what *exactly*
you want to think about. The sun produces enough energy
in ~50 years to break/recast all of the atomic bonds
in the non-stellar material. So in that time frame
(or less if you are clever about chemical transformations)
you can "rearchitect" your computers to think optimally
about something completely different.
It is interesting if you consider the growth curve --
nonexistant, slow, somewhat faster, exponential, very slow.
(That is over a ~5-6 billion year period if we are typical.)
However the "growth curve" may be disconnected from the
"thought/knowledge curve" in ways we cannot currently comprehend.
