One important note about techincal progress and innovation that Marx noticed and i rarily seen mentioned, is that contrary to most widespread myth of economical progress following innovation, it is actually in the other way - innovation follows the needs created by the economy. Marx observed that while analysing the industrial revolution, but it was also clear for the earlier epochs (just it happened usually way slower then) - this is also an explanation why progress was so fast in the last two centuries and why today some things are still improving in blinding tempo, but some are stagnating.

Of course it's because the driving force in capitalism - profits, and because what comrade Kaffe wrote about development of capitalism itself, it looked different when the capitalism itself was a fresh progressive force, and entirely different when an entrenched mono and oligopolies are stiffling innovation with patents, copyright, buying inventions, industrial sabotage etc.
