As a counterpoint, things we rely on like Amazon are actually a lot of tiny businesses that have ideas and now we are able to get their more tailored products, whereas two decades ago, I just got to buy whatever walmart or bestbuy was willing to sell us.
Also consider youtube, I watch a lot of tiny creators and two decades ago the only thing available was the major tv networks and cable tv.
It may be true that big organizations deliver these things, but big organizations delivered them before and it’s definitely more possible for small organizations to have big impacts now than it was before.
