Tech was ruined in the 90s when capitalistic influences (microsoft being the dominant force but far from the only one) propagandized the industry and eventually populace at large with the idea that competition in the industry is what drives innovation.
Granted, much of their work was already done for them thanks to western influence perpetuating this ideal for ages. But when the frameworks for open standards, interoperability, and collaborative development were being proposed and put into place they were shot down and/or actively sabotaged
As a result 40 years later we have this mess. A landscape filled with nightmare tech. Fragmentation everywhere, design heavily influenced by a small handful of sociopaths with no empathy and active disdain for users, the idea of open standards is something that requires government intervention (and still rarely occurs), interoperability is something that has to be hacked around and frequently breaks as a means to encourage purchasing a competing product.
What could have been. Tech designed for people’s needs rather than tech designed to extract income
