Welcome back to the Week That Was series highlighting things from the interwebs which are interesting, noteworthy and/or probably worth your time.

Articles๐Ÿ“, Tweet(s)๐Ÿ“ฑ, Videos๐ŸŽฅ, Charts ๐Ÿ“ˆ all fair game with or without attendant commentary.


๐ŸŒ๐Ÿš€ Africa’s Startup Activity

Statista put together this graphic showing where Africa’s startup activity in terms of venture capital investment is concentrated - per a report AfricArena published using Partech data.

The big four still attract the vast majority of investment i.e., Kenya, Nigeria, South Africa and Egypt.

Per the Disrupt Africa report (which has fairly divergent total numbers to the aforementioned AfricArena one it should be noted) here are a few more specific breakdowns of the investments.

That said, interestingly entertainment startups received record investment last year.

๐Ÿ“น๐Ÿค” The Tail End

Kurzgesagt returns with a thoughtful and slightly melancholy piece.

Wrapping your mind around your life is pretty hard, because you are up to your neck in it. It’s like trying to understand the ocean while learning how to swim. On most days you are busy just keeping your head above water. So, it is not easy to figure out what to do with your life and how to spend your time.

There are a million distractions. Your family, friends and romantic partners, boring work, and exciting projects. Video games to play and books to read. And then there is your couch that somebody needs to lie on. Itโ€™s easy to get lost. So let us take a step back and take a look at your life from the outside.


๐Ÿ˜ฌ Blunders

Michael Nielsen notes that based on some analysis done on 25 million positions in chess, the blunder rate increases the longer players take to decide on their next move.


Of course, correlation doesn’t necessarily imply causation as noted by a commenter on the paper given more time tends to be taken on more difficult positions - and as such more mistakes are likely.

The image then is both a caution against making the real blunder of assigning non-existent causality when doing observational study - and also an interesting academic/empirical confirmation of something we get anecdotally: when the decision is a difficult one, often spending significantly more time trying to make the decision is unlikely to yield a significantly better result.

Mark Maggiori’s work, which focuses on the outback culture, is often mesmerising - particularly his use of clouds and lighting. Another example.

๐Ÿ“‰๐Ÿ’ฐ Labourless Growth

Companies continue to get more and more efficient - with commensurate wealth bifurcation as the capital owners of mega-corps which triumph in winner-take-all markets accrue astounding financial power.

The S&P 500 is 70% less labour-intensive than it was 35 years ago - the classic labourless growth which is one of the many powder-kegs destabilising modern-day politics.

Allumuah [Pronounced: โ€˜A-Loom-Wahโ€™] is an experimental short film (04:23) by Curtis Essel that explores the path of intersectional/generational relationships which vividly depicts the beauty in culture and the characters within it.

๐Ÿข๐Ÿ ๐Ÿ‘จโ€๐Ÿ’ป Return To The Office

Andreesen Horowitz did a survey of their portfolio companies regarding their post-covid office plans.

Some highlights - which they noted in their blog

Whatโ€™s your likely plan with employees in the future post-COVID?


If you are enabling hybrid work post-COVID, how often will you require people to be in the office?


If you did not hire remote workers before COVID, are you now?


Do you think your company can be as innovative and creative in a remote or hybrid work environment?



๐ŸŽ™๏ธ๐ŸŽง Computer Science, Crypto & Philosophy

Lex Fridman breaks his previous podcasting record with this five hour (๐Ÿ˜ฎ) ultra-nerdy deep-dive into everything from mathematics and simulation theory to cryptocurrency mechanics and philosophy - with Cardano ($ADA) creator Charles Hoskinson.

Lots of Bitcoin Maxis actively hate Hoskinson, and consider him a scammer & “shitcoiner” (presumably because he’s generally very disparaging of the BTC protocol while promulgating a (pre-mined) purported 3rd generation one of his own).

Personally I think it’ll be hard not to learn at least something from this wide-ranging and fascinating discussion; whichever side of the crypto moat you find yourself.
