I've read some tech debates in this thread that are above my pay grade, but I largely agree with the title. Case in point, the same discussions in this thread that are above my pay grade drove the building of our startup as a browser-based PWA, instead of two native apps.
Certainly native apps would have been better as a 'perfect solution', and we're still looking at building them in the future, but for delivering a working MVP it didn't make sense to even attempt. I suspect this will apply to many/most app startups going forward, and that means between native apps and PWAs, the browser is the marketplace of first-to-market products.
