That's still far too low. It should be in the high 90th percentile, where everyone who wants or needs to use it can. When three quarters of the population of a country have no access even if they want it its a sign that more needs to happen.
Even in OECD countries, 26% of people aged 16-65 failed a test designed to gauge computer skills because they couldn’t use a computer at all:
Being too polite to use a term like “level zero,” the OECD researchers refer to the lowest skill level as “below level 1.”
…
An example of task at this level is “Delete this email message” in an email app."""
That 26% I described? They were below even the “Below Level 1” level.
Feel free to consider this a bet to come back to.
Cell phones, for example, are widely used in developing nations. Tech in general has been the best at reducing costs over time compared to things like food and energy which haven't really fallen in price.
€600 for an entire village/favela/whatever else to have some form of internet sounds fairly reasonable in the early 21st century. And prices will surely go down over the next few years.
That said, given the base station is currently sold below cost, it may take quite a while to get cheap.
