I don't know where you're from, but in place where I live, I wouldn't say that things is getting worse here. I would say that significantly less people smoke nowadays than it was 15-20 years ago. It's not just people's mindset is changing, but it's also getting too expensive to smoke.
But on the other hand more people starting to smoke things like IQOS, vapes and weed also. Not sure what is more harmful, but trends is changing. Curreent generation ternagers don't even look at these old school cigarettes.

Reversible computation is a concept in computer science that refers to the ability to compute both forward and backward through a given computation. In reversible computing, operations are designed in a way that allows for perfect information preservation, meaning that no information is lost or destroyed during the computation.

While reversible computation has been an area of research and interest in the field of computer science, it is important to note that it is not yet widely implemented in mainstream computing systems. Most modern computers and electronic devices use irreversible computation, where information is lost through processes like heat dissipation and energy consumption.

That said, reversible computation holds potential benefits and applications, particularly in areas such as quantum computing, low-power computing, and fault-tolerant computing. Some potential advantages of reversible computation include energy efficiency, increased computational speed, and the potential for error correction.

In the field of quantum computing, where information is stored and manipulated using quantum bits (qubits) that can exist in multiple states simultaneously, the concept of reversibility is fundamental. Reversible operations are essential for maintaining the coherence of quantum states and enabling quantum algorithms.

While reversible computation shows promise in certain contexts, there are also challenges and limitations to its widespread adoption. Implementing reversible computation requires specialized hardware and design considerations, which may come with additional costs and complexity. Furthermore, not all computational tasks can be easily expressed in a reversible manner.

Overall, while reversible computation is an intriguing concept with potential applications, its widespread adoption and realization as "the future" of computing will depend on advancements in hardware design, algorithms, and the specific needs and trade-offs of different computing domains.
