Lex Friedman asks what an app is worth now that we have AI:

The answer, to me, is you pay for an app if the care and attention the developer gives the app is more than you can afford to give. If the few bucks you’ll spend is worth more than the time you’d spend building your own version of the app.

Most people just don’t have time to maintain an app. The value of one-off utility apps will go down, but there will still be a market for many kinds of apps, especially those with an ecosystem or significant infrastructure behind them.
