Why does industry lag in adopting technological advancements?

Many industries still rely on separation technology that is two to three decades old. While this technology is reliable and technically sound, it is akin to driving a car that is two to three decades old. At first glance, the basic principles may seem similar, but a closer examination reveals significant differences. Comparing an old car to a new one, you will notice the latter's additional safety features, compact design, fuel efficiency, and lower emissions not to mention other benefits. Likewise, advanced separation technologies share similar traits: they occupy less space, resulting in a smaller carbon footprint; they demand less energy, enhancing efficiency; and they offer superior separation performance, which benefits the environment. Most people don't regularly use vehicles that are more than two to three decades old unless they are classic cars reserved for special occasions or weekend drives. So, why does the industry lag in adopting these advancements?
