A new foundational crisis in mathematics, is it really happening?

TL;DR

The paper argues that the discovery of Homotopy Type Theory (HoTT) does not signify a foundational crisis in mathematics, supporting a pluralist view of mathematical foundations.

Contribution

It provides a detailed analysis of HoTT's mathematical basis and its relation to existing foundations, challenging claims of a crisis.

Findings

HoTT does not undermine existing foundations

The perceived crisis is a misunderstanding

Supports a pluralist approach to foundations

Abstract

The article reconsiders the position of the foundations of mathematics after the discovery of HoTT. Discussion that this discovery has generated in the community of mathematicians, philosophers and computer scientists might indicate a new crisis in the foundation of mathematics. By examining the mathematical facts behind HoTT and their relation with the existing foundations, we conclude that the present crisis is not one. We reiterate a pluralist vision of the foundations of mathematics. The article contains a short survey of the mathematical and historical background needed to understand the main tenets of the foundational issues.
