In software, there has always been a line between people who understand how computers work and people who learned a framework as a trade. AI did not erase that distinction. It made it more obvious.<br>From my point of view, and from my own experience, there has always been a clear difference in software between two kinds of professionals: those who understand how computers work, and those who learned a framework as a trade and built a career around it. That distinction can make a company work, help it succeed, or send it into disaster very quickly. Having engineers on your team who can work across multiple areas, think through a solution from beginning to end, and understand how the pieces connect is an excellent sign.

Technology was never as static as other industries, and today it is even less so. Decades ago, an air conditioning installer could spend an entire career doing only that without needing to understand much about electricity, plumbing, architecture, or the broader system around the job. In some ways, that mentality moved almost naturally into software. For example, for almost a decade, many Flash developers lived inside a bubble. It looked like knowing Flash was enough to have a very well-paid job. But when the platform started collapsing after 2008, it became clear who understood systems and who had only learned a tool. Most developers from that era were simply bootstrappers. Very few were true craftsmen of the Flash trade, and those were engineers who understood systems very well, many systems, not just one, well enough to push ActionScript to its limits.

Another example: when I started this profession as an engineer, or hacker, more than 27 years ago (yes, I am old), there were specialists for everything, and I had become one of them. But I had no limits when it came to learning, and I always got involved in everything. I was lucky to be surrounded by hackers and to learn from them, to pay attention, to not be afraid of installing a new operating system, writing my first lines in a new programming language, or trying a new software architecture. That habit of trying new things and understanding how they worked opened doors in every part of my career.

But not everyone had that same spirit. Most people had only put in the effort required to learn the basics of a platform, and then they became the usual sedentary professionals. The developer who only worked on frontend only touched HTML and CSS, and that was it. They knew nothing else, and that was exactly how they were valued. Backend engineers wanted nothing to do with frontend, and vice versa. Many backend developers barely understood backend, because backend is not just building REST APIs. There is data modeling, and for that, there was also a specialist who wrote queries. There is infrastructure, security, deployment, observability, performance, and a long list of other concerns. Everything was so fragmented that companies could barely function unless they had an enormous team where every person existed to change one comma in one specific backend function. Even inside backend, there was always someone who had spent their entire life working on one module, and nobody else on the team had even inspected what that thing was. The fear of touching something and breaking it was always in the room.

On paper, that dynamic can look almost generous, because one might think all those people had jobs. In practice, it was far more harmful to them than people realize. Projects died very easily, and everyone ended up out of work because the company could not operate without that swarm of narrowly specialized workers. If Bob got sick, the whole team fell apart. John, who was also on the team, knew nothing about HTML or CSS beyond the basic concepts, because he only wrote PHP. But do not ask John to write HTML or CSS, because he only understands databases and SQL. As you can see, many of the people we called engineers were actually bootstrappers: specialists in one platform, helpless everywhere else.

That kind of professional is the least fungible. It made sense in the past, when everything was a mess and having someone who knew a lot about HTML and CSS made a real difference because of browser inconsistencies, rendering engine bugs, and all the strange problems of that era. But today, that problem and many others no longer exist in the same way.

Some people will remember the title “fullstack,” those renegades who were often disliked by their peers because they were reckless enough to touch every piece of the puzzle. I still remember the dismissive comments from former coworkers when they had to give an opinion about “the engineer who can touch everything.” The comments sounded like the usual American version of “jack of all trades, master of none.” I include myself here, because I repeated that line too, almost out of...
