Now Japan faces a lavor shortage, but smart technology will help to solve this problem. In some workplaces such as hotels or banks, employees can already reduce the burden with AI and robots. If human employees at the counter spend many hours on repeating a series of the same and simple tasks and get tired, then the employees can leave parts of the simple tasks to the robots and feel free of stresses and strains, which will lead to the improvement of quality of life as well. Also if self-driving buses become more popular they will surely help to solve a shortage of bus drivers and at the same time they will improve the working conditions drastically.
smart technology will solve this problemでもよいのですが、直接的な解決ではなく「解決の一助になる」というニュアンスを出すため help to を入れました。

Last year I failed to be a student of Osaka University. I was deeply disappointed but decided to study again in order to be enrolled in Osaka University. It was very hard to keep studying while my friends who were already college students were playing. Now I believe I will pass this test. That's because I never gave up my dream and continued to study.
