It also gives you a lot more free time if you can persuade your employer to let you use cutting edge technology rather than needing to save it for your side projects after hours.
Plus, given how many startups fail, you do kinda need a backup plan...
So, I suspect a lot of companies are... encouraged to aim for scale and encouraged to tackle problems in the most overcomplicated way possible so that the people working there can take their experience to Alphabet/Meta/Apple/whatever if things go south.
I think it's more that people are attracted to tractable problems. We like to follow certain paths that are well-worn, where the next step is visible and easy to see. And whether those paths lead to a pretend/pointless destination is, surprisingly, irrelevant. They're easier to follow than whacking our way through the brush.
Are you kidding, have you seen the C programming language?!
