True
But there are other tech related jobs that are linked to AV companies…jobs like a software engineer, technology innovators and so on. Even the mechanics will earn more because it requires a lot of regular maintenance.
There is nothing that has its advantages that does not have its disadvantages. But I still feel like it has more pros than cons and it does more good than harm.

I understand, but you know not everyone can become engineers too, I however agree about having more advantage than disadvantages. Cheers to a beautiful weekend.
