I could agree that modern technology and the industrial revolution are very similar. But even with that it has taken 60+yrs for our society to have a computer in the majority of homes after the Manchester Baby was created (and I think this change happened extremely quickly). And, analog and electromechanical computers go back even further. So, again, I think even these things have been a very gradual change happening over many decades once the leading technology was invented.
To further expand on my thoughts, to imply everyone was using ‘industrial revolution’ technology overnight would be heresy. I’m sure it took factories many decades to build and retrofit equipment including a technology run up to the revolution itself. With this said, you peaked my interest in this area and I have some researching to do this weekend.
