[FMA] If FMA universe continued into the technology age, how different would the FMA universe be?

I've read that alchemy is applying the concept of deconstruction and reconstruction where you have to fully know and understand the properties of the material, that's why only those dedicated enough were able to become alchemists in the universe.

As for my question, in our current world, there's this huge knowledge gap in what we knew 100 years ago to what we know today where things we couldn't imagine existed were proven true. It shouldn't be too far-fetched to imagine that the same thing could happen in the FMA universe. Assuming they'd eventually reach the technological age, there'd also be the ease of information through the internet which makes it easier to learn alchemy. This would make learning alchemy available to a lot more people and probably easier to learn compared to learning it during their time. 

But, since we see only a few people in the FMA stories who actually practice alchemy, it may be because it's too difficult like learning quantum physics, for example. So do you think that the sheer difficulty of learning alchemy would people away or be the constraint for people learning it? Although, even if it is difficult to learn, it has a huge amount of benefits it can bring to the user. For example, fixing broken things instead of throwing them away, or other ease of life things I can't imagine at the moment. Also, considering the destructive capabilities of alchemy, would it be heavily regulated by the government if ever people will try to use it? I'd imagine there'd be more rules similar to "not transmuting gold" and harsher implementation too due to the larger amount of people who can use alchemy.

They allude to it in FMA. They will never enter the industrial age because they dont have to. They have alchemists capable of producing enough to meet peoples needs, so factories never became a necessity for production.
