I've had eczema for 40 years. It's gotten much more manageable with age, but I'm still allergic to a few things, such as dogs.

I'd much rather be alive and dogless, than dead in the first year as was common before modern standards of hygiene.

Modern life has bugs, but modern technology can help produce bugfixes. Perhaps in the next few decades it will become common practice to expose babies to a range of relatively harmless pathogens to train their immune system, just like we vaccinate them now against more deadly diseases. Perhaps as we learn more about our own gut flora, we will develop a way to add or subtract specific strains of bacteria to bring about a desired result, instead of eating random "probiotics" to hack the immune system in the dark.

I'd be much more optimistic about such solutions gaining traction, both scientifically and commercially, than the prospects of telling everyone to go roll their kids in dirt. That's just the way modernity works. It doesn't like to stop and look back. It barges ahead, update after update, fixing bugs as it goes along.
