Yes, there are a handful of downsides. Like any machine, computers can break. They also require electricity to operate, so they won't work if there is no power. That leads to another problem, and that is an excessive dependence on computers. So when the power goes out, we may feel lost. Excessive dependence on computers can set us up for safety problems too. You've probably heard of people driving with GPS systems and driving off of cliffs. That proves it is easy to get mentally lazy and let computers be a place for common sense.
Then there are other problems such as computers getting incompatible with software and new hardware as time passes. When newer hardware components are made, they don't always work with older computers. So if a part goes bad, then you have to replace other things to get the replacement part to fit and work. Then newer operating systems require newer hardware, and if you want/need to run the latest version of whatever operating system, then you will be forced to upgrade. Even the OS writers set things up in such a way to where you have to upgrade your OS. That may force you to upgrade your PC too, and if you get a new PC or significantly modify it, you may be forced to purchase a new OS.
