I don't agree with that. They made the PC revolution possible by making hardware that was at least affordable enough to be bought by a large number of businesses and individuals. It also set the stage for the clone market. I'm pretty sure that if IBM really set their mind to it that they could do this.
That doesn't detract from your overall point that they tend to make overpriced stuff, but I don't think they have to do that. Besides, what's overpriced? NVidia's GB300 workstation sells for 95K euros, a single RTX 6000 is now 20K. Surely even IBM can compete at that level.
Respectfully, those people don't work at IBM anymore. The organizational memory doesn't last that long.
It's the "PC-compatible" hardware make those affordable, not PC.
> They made the PC revolution possible
Yeah they were only half a decade late to the PC revolution back in the day...
That was completely accidental and they themselves tried to close the barn door with the PS/2 line in 1987 but at that point it was too late.
