When i was there, two decades ago, people were making presentations internally saying the same thing - "without affordable volume machines that random people can buy and use to develop, this ecosystem will fail"
Then, like now, there were even organizations/companies people thought might eventually take care of doing this that weren't IBM (Spoiler alert: They didn't)
Given that it has been at least two decades, i'm not sure whether that makes the doomsayers wrong or right.
But I am sure of one thing: IBM didn't care to do it then, and doesn't seem likely to start caring to do it now
