Once the single-focus companies have to actually make a profit and flip the switch from poorly monetized to fully monetized, I think folks will be immediately jumping ship to mega-companies like Google who can indefinitely sustain the freemium model. The single-focus services are going to be Hell to use once the free rides end: price hikes, stingy limits, and ads everywhere.
.... but the field will change unpredictably. Amazon offers a lot of random junk with Prime -- hike price $50/year, slap on a subscription to high-grade AI chatbot 10% of users will actually use (say 2% are "heavy users"), and now Anthropic is financially sustainable. Maybe NYT goes from $400 to $500 per year, and now you get ChatGPT Pro, so everything's fine at OpenAI. There're a ton of financial ideas you'll come up with once you feel the fire at your feet; maybe the US government will take a stake and start shilling services when you file taxes. Do you want the $250 Patriot Package charged against your tax refund, or are we throwing this in the evidence pile containing your Casio F91-W purchase and tribal tattoos?
