How comparable is the 2nd amendment with technological advances in firearms?

Many have argued for restrictions on the kinds of guns people could own such as assault weapons because they possessed too much fire-power. When pro-gun advocates bring up the second amendment, proponents of firearm restrictions will say that the founding fathers didn't know that weapons could have as much firepower as a modern assault rifle. Pro-gun advocates will then say that they couldn't have envisioned that the internet would be able to spread people's views as far and fast as they did but that doesn't justify restrictions on free speech across the internet (although some are trying to violate social media sites first amendment rights by forcing them to platform their message, but that's another story).

But here's the elephant in the room: when the constitution was written, pretty much all states had laws that prohibited private citizens from owning cannons so there is indeed a precedent for firearm restrictions in the legal framework laid out in colonial times. What are your thoughts on the topic?
