This article is using its terms in a specific way. By "tech sector," it sounds like he's talking about large technology companies that have been valued by the market at higher multiples than the older "blue chips," big stable companies.<p>By Malthusian, he means "large and mature enough to be limited by the size of the market."<p>The trigger for the thought seems to be that some newer "tech" companies are operationally more similar to traditional blue chips. Tesla is more like BMW and netflix is like hbo.<p>So, anyway idk....<p>Tech is valued so highly for a bunch of reasons. But, those aside, there are factors unrelated to sector.<p>Tesla, netflix and such are new companies. Coca Cola, GM & BMW are old. They run gradualist, conservative starters.<p>Netflix and Tesla are far more likely to pull a rabbit out of a hat. It's in their culture. The whole company was in the hat 5 minutes ago. Assuming that Tesla and BMW have similar future potential is (perhaps) academic, because they'd never pursue them anyway. Netflix might attempt a pivot to being a game company, if the opportunity was attractive. HBO probably couldn't.<p>Even IBM is a good example, the one tech company that's old-ish and has a "blue chip" persona. They managed to pivot into consulting. Would coca cola have successfully pivoted into fresh food delivery?<p>There's a flexibility in tech that doesn't exist elsewhere.<p>Also, I suspect, the way most large companies are growing is overly risk averse. Tech can't be derisked to that extent, so the companies pursue the higher value, higher risk strategies.<p>The best example to sum this up is Amazon and their 2nd act Aws twist. You might compare amazon of 2016 to other retailers. Walmart never had the potential to launch an Aws.<p>When tech is everywhere, the article thinks the tech sector doesn't exist. The opposite is possible too. When everything is tech, the tech sector owns everything.<p>Ultimately, coca cola is a legacy company.
