Mainframes were followed by PCs, and then the web, and then smartphones. Each of these new models started out looking limited and insignificant, but each of them unlocked a new market that was so much bigger that it pulled in all of the investment, innovation and company creation and so grew to overtake the old one. Meanwhile, the old models didn’t go away, and neither, mostly, did the companies that had been created by them. Mainframes are still a big business and so is IBM; PCs are still a big business and so is Microsoft. But they don’t set the agenda anymore - no-one is afraid of them.

We’ve spent the last few decades getting to the point that we can now give everyone on earth a cheap, reliable, easy-to-use pocket computer with access to a global information network.

On a job site, they’re the provisioners of positions and never miss the chance to regale their audience with their professional deeds: hiring a teenager with no experience, giving a stressed single mother a chance to provide for her family, or seeing past a candidate’s imperfections to give them a once-in-a-lifetime opportunity. These stories are relayed dramatically in what’s now recognizable as LinkedIn-style storytelling, one spaced sentence at a time, told by job-givers with a savior complex.
