One universal antiviral to rule them all?

Wont viruses just adapt and now we've got worse viruses as a result? Isn't this kind of why doctors don't like to prescribe antibiotics too often, because they become ineffective in the long run.

I'm genuinely asking, I'm a simple software dev not a doctor.

Is it really true that we have “worse” viruses, or that they are adapting to our modern antibiotic regime & reverting to the status quo?

Antibiotics have never killed any viruses ever. They are exclusively for treating bacterial infections (which are generally worse by a lot).

Azithromycin (rhinovirus, influenza A, Zika), clarithromycin (influenza A, rhinovirus), doxycycline (dengue, Zika), minocycline (West Nile), teicoplanin/dalbavancin (Ebola, MERS/SARS-CoV and SARS-CoV-2), rifampin/rifamycins (orthopoxviruses), aminoglycosides (HSV-2, influenza A, Zika), salinomycin/monensin (influenza A/B, coronaviruses incl. SARS-CoV-2), nanchangmycin (Zika, West Nile, dengue, chikungunya), nitroxoline (mpox), and some fluoroquinolones have all shown antiviral properties.

And no, strep throat is not worse than ebola.
