Anyone that was around for the "Turn of the Century Crash" may find this familiar.
With all the massive scaleups, companies were becoming bloated as hell. They also became fairly sloppy with their money.
Time to pay the piper.
But unlike some bubbles, there's a real industry, here (like in the 'oughts). It's a return to a [still pretty decent] baseline, as opposed to an implosion to nothing.
In the early Web days, the money started to become silly, and people were thronging to the industry, despite having no qualifications, and no passion for the tech. They just wanted money.
Basically, they were expensive, and they sucked (sound familiar?). Most were Web developers, or around the process of creating and maintaining Web presence.
Also, some people were very, very good, and some marvelous tools came of it.
This is like the Late Devonian extinction. The table needed to be cleared off, to give rise to the new.
The company that I worked for, had survived being fire-bombed during the war, a major depression, and multiple recessions. They were absolute tightwads.
At one point, they started making a whole lot of money, and got silly.
Piper, meet company.
They have basically contracted back to what they were. Everyone is writing them off, but I'll bet they come out of the scrum, OK.
Same with the tech industry.
