As long as highly skilled human labour remains necessary to design the machines that build other machines, full automation of the production process will not happen. In this scenario the effect of distributing profits as I have described would be to ensure that prices remain more or less stable while incomes rise, with the result that products become increasingly more affordable.
And if it ever happens that the production process does become fully robotized, with humans no longer needing to work on the design or the manufacture of the robots that make other robots, then all prices and all incomes will gradually recede until every product is like the air we breathe: so plentiful that no one needs to pay for it, however precious it may be.
