I realize, but the idea that we won't have another giant company succeeding at achieving the same seems like wishful thinking.

Making sure another company doesn't get into the same position is precisely what antitrust laws and enforcement agencies are for.

The only reason why we have the mess we do is because we have made our antitrust toothless starting in 1980s, and it's only gradually coming back now.
