"But if Netflix and Walt Disney both use technology to stream video, why is only Netflix trading at infinity-times earnings? And if Tesla and BMW “both use battery technology to power luxury cars,” Deluard writes, “why should the former trade at 42 times forward earnings when the latter fetches 5.6 times trailing earnings?” Good question."
Incredibly flawed argument. BMW's earnings come from a huge variety of products and services. Not purely battery-powered electric cars. Tesla's entire business model is producing battery-powered vehicles.
So to compare each company's P/E directly under the assumption that they are both making identical products would be wrong. Instead you would need to somehow isolate the P/E ratio of BMW's battery-powered car business in order to draw a meaningful comparison.
In general, this article is trying to group all of tech into one basket and draw conclusions which apply universally. A company has a high P/E ratio for a very simple reason: investors believe its earnings growth will outpace the market. That will seemingly always be true for companies which are focusing on growth over profit.
