Granted the criticism that Hoyle's calculations addressed the improbability of the spontaneous generation of a fully formed bacterium rather than abiogenesis starting with simpler organic molecules, simultaneous trials, etc., insurmountable difficulties remain for such abiogenesis.
For example, the following are "reversible condensation reactions":
amino acid + amino acid <==> protein + water
nucleotide + nucleotide <==> DNA + water
"Every first-year chemistry student is taught that reversible chemical reactions will never proceed in a direction that produces a product that is already present in excess amounts in the reaction vessel. The production of DNA and proteins from their building blocks results in the production of a large number of water molecules. A problem for the oceanic vent theory (or any water based primordial soup theory) is that there is already an abundance of water. Consequently, the reaction above will never proceed in a direction which produces more water. In fact, the laws of chemistry and thermodynamics demand that the reaction go in the opposite direction! Therefore, in a watery solution containing the building blocks of life, the overwhelming majority of these building blocks would be unbonded. As a result, a watery environment is perhaps the last place that long chains of amino acids or nucleotides would form."
