There's a long list of construction startups who thought the industry was low-tech simply because everyone in it was dumb, and that they would be the smartest guys in the room who'd revolutionize everything. Those startups are pretty much all roadkill.

Tesla has had great engineering from day one, but almost went under because it couldn't figure out large scale manufacturing and logistics. Problems that old school companies have been solving for a century.
