It could be if you don't discard his qualifier "from a physical

I wasn't even talking about this macroscopic level of energy efficiency.
What James and I were discussing was at the microscopic level. I was
suggesting that "if photosynthesis isn't efficient enough to power a
small device, then perhaps that small device needs to be engineered to
require less power while accomplishing the same task" ... and James is
asserting that modern technology is already reaching (or has reached)
their limits.
To James, I say: Some laws were meant to be broken. I firmly believe
that the laws of thermodynamics are not true laws of nature, but just
a stop-gap milestone in our understanding of the physical world with
which we interact. We will discover that even the laws of
thermodynamics don't hold as laws at a certain level, and we'll make
a great breakthrough that will totally change the way we manipulate
our physical surroundings.
My only curiousity is if this breakthrough will occur in my lifetime.
If the sentiment that you hold, that the laws of thermodynamics are
indeed strong laws and are a limiting factor, is widespread amongst
the scientific community, then sadly I say I doubt it WILL happen
within my lifetime.
