While memory safety can help reduce many security vulnerabilities it is not the only source of vulnerabilities. Furthermore as for getting hacked I would suspect the main problems to be social engineering, bad configuration and lack of maintenance and not really the software itself being insecure.

No one should blindly upgrade because bigger number is better. If I look into new hardware I research benchmarks and figure out if it would enable me to (better) run the software/games I care about it and if the improvement is worth my money.

Same with security. You need to read actual studies and figure out what the cost/benefit of certain measures is.

There are safer alternatives to Linux but apparently the situation isn't bad enough for people to switch to them.

And I am not saying you should create new projects in C or C++. Most people should not. But there is a lot of battle tested C and C++ code out there and to act as if we suddenly have this big problem with memory safety is a weird narrative to push. And if you discover a vulnerability, well fix it instead of wrapping it Fil-C and making the whole thing slower.
