tutorial is a bit tricky, as my setup is for obsolete handset (Honor 3C), but i guess we can put together something recent.
If that is the goal, then it is sheer stupidity.
Desperate people often think they have nothing left to lose. Whether this is stupidity, or a wisdom, time will tell. I'm not so sure about pundits denouncing current trumps policy just yet. Despite how outrageous it is, it has little to no practical impact. The impact of wages >120k for H1B immigrants is much, much higher and the true point of contention.
On the other hand, if you look at the actual countries banned, and the actual number of workers involved in the ban (some of the tech giants publicized this number), you see that the impact is rather low (bulk of H1B tech immigration is asia, definitely not egypt). Basically you're jumping to conclusions based on petty gesture policy.
quarterly repots and stock flipping
Short sightedness and excessive risk aversity are consequences, I'm interested in inherent causes of it. Calling it "greed" is a bit too nebulous - there's always profit motive, regardless of market strategy.
Running a company isn't a netflix binge.
Gigabit to entire towns is a loss-maker not just in terms of decades.
The long haul costs are pretty trivial these days, the problem is still mostly last mile. Not in terms of technology, but legislation, leases, slush fund to get dig/pole permits and more, and that is assuming there are no state ordinances explicitly foiling metro net development like it is common in the US.
It indeed is similiar to real estate development in many ways. Needless to say UK has one of the most fucked up real estate markets, no surprise last mile competition is effectively nil.
Any infrastructure like that is basically loss-making for DECADES
Northern, central and part of eastern europe beg to differ, ROI for city is 3-6 months/cust, distant rural areas about 8-16 mo/cust. A lot of ISPs cover that by contract clauses, so they are guaranteed to get their break even money always.
City metro telcos + high speed wifi routinely cover 30% of population. The secret to it is commieblocks and just-in-time infra deployment - not sure how exactly that is viable in the UK, but in here, FTTX can be done for very cheap in densely populated cities, and those cover good chunk of population.
Remote areas get internet 2x more expensive, but still very cheap - mostly as a consequence of cut-throat urban competition, ISPs are forced to branch out into rural areas.
The bogosity meter just pegged.
