Yes, I think most inventions do bring benefits. For example, medical advancements have greatly improved our quality of life by curing diseases and extending life expectancy. Technological inventions, like computers and smartphones, make our daily tasks easier and more efficient. They also help solve global issues, like renewable energy technologies that address climate change. Plus, inventions often lead to economic growth and create new jobs.

No, not all inventions are beneficial. Some have negative impacts, like plastic, which harms the environment. Technological advancements can also lead to job loss due to automation. There are ethical concerns too, as some inventions can be misused. Additionally, not everyone has access to all inventions, which creates inequality. And some inventions, like processed foods, can lead to health issues.

It really depends on the invention. Some inventions can have both positive and negative effects. For example, the internet has revolutionized communication but also raised privacy concerns. The impact of an invention often depends on how it's used and regulated. Over time, inventions can evolve to become more beneficial or harmful. Public perception and how people adapt to an invention also influence its benefits.
